My son has always been a tricky sleeper, from his 3rd birthday starting waking up in the night 2-3 times. I'm so glad I gave this clock a try it's worked for us as he is now sleeping through the night. Book really helps to explain the clock. Overall really happy! My advise would be give it time it was probably 4 weeks before things started to change.

Great to let the little ones when it's time to get up

Little bit complicated to get used to at first, didn't take long to get used to. Managed to set 2 times one for week days and the other for weekends
Would definitely recommend

Sun and stars.... and yellow ...yes

I love this clock when it does its job.......

My boy is 3.5 we had this a year and still trying to get him to understand it. I think I've figured it out... instead of saying sun and stars..... I'm now saying blue and yellow which is working better. If the clock is blue go back to bed when the clock is yellow you can come tor mummy. He still comes in and when I ask what colour the clock is he says blue I say then go back to bed and he will go now. Before ....stay in bed until all the stars have gone and the sun wakes up, he would scream and cry about having to go back to bed.

Also why not battery operated. ain't stupid and know how to switch off.

sanity saving technology

With 4 children life is busy to say the least. 2 out of the 4 like to wake at stupid o clock to start their day. No amount of pursuading would make them go back to bed so someone recommended a gro clock. First of all we bought a stupid character one that drained batteries and didn't do the job so then we got the gro clock. Best thing we ever did. The story is great for explaining although could do with being a bit more durable. The clock itself is lovely. The kids can press the button to say goodnight to the sun and then you lock it so the horrors can't turn it off. Set the time to the time you want them up and they lay in bed waiting for the sun. When the clock changes you here screams of the sun's up as them come charging in to see you.


Bought this for our Eldest son who liked to get himself and everyone in the house up at a silly time in the morning but after we got it he Stayed in bed until the sun came up and now even tells his little brother to stay until the sun comes up.

excellent wish it had battery option

Wonderful idea brilliantly executed, really nice product and most importantly it works. Only request is please make a battery powered one so we can loose the wires and even better. take it on holiday!

Amazing purchase

Do you enjoy sleeping? We did, until our little boy thought that 5am was a good time to begin his day. A few friends had told me of the wonder of the Gro Clock & it'a powers of keeping toddlers in bed a bit longer.

I have to say I was sceptical to start with, my little boy after all appeared to have adjusted his body clock to think 5am was perfectly acceptable & no amount of pleading or bribing was going to convince him back in bed.

I explained how the clock worked & read him the story. To begin with I set a realistic time for him so that he could get a sense of achievement when we applauded him for waiting for the sun. He would shout "mummy my sun is up, come & see". We gradually increased the time each day until we got it to 7am on a nursery morning & an amazing 8am on his days off. It most definitely works....thank you thank you thank you!

fantastic product

This product has the best features it has great quality for the price.

My son is addicted!

We got this for our son when he was about 5 months old after a friend raved about it. I thought he was too young but got it anyway as it was on offer. We liked the routine if nothing else. He is now 16 months old & he LOVES his clock! When he's "let loose" in his nursery, the first thing he wants to do is click the buttons & watch it change from the sun to the blue background. We read him Sleepy Farm every night, which he also loves, and looks over to the clock and smiles every time it changes. He already knows that it's not time to get up until the sun has come up, and I think starting early will set us in good stead for when we take the sides off his cot (not for some time yet, mind!) I'll definitely be getting another one for number 2!


We brought this for our son for his 2nd birthday! He was waking in the night and early in the am but now that's a thing of the past! He uses the clock in the night to help him realise it's sleep time and if he wakes he knows not to call out until "the sun shines awake"! He loves turning it on himself but with the lock function he can't change it in the night! It's lovely that it can also be used as a night light or with the light off so it's dark!
It's super easy for adults to set up takes mere minutes! Would and have recommended to all!


Bought this for my 2.5 year old daughter when new baby was born as his crying would sometimes wake her up and she thought it was morning. She now understands that if it's still the star then she needs to go back to sleep.
Might just have been pure luck but it worked from the very first night :) she woke at 5am (I was up feeding baby and watched her on the video monitor) looked at her clock and turned over to go back to sleep! :)

Every gro product we have bought has been absolutely fantastic! The groclock, groegg, gro bags with both babies, gro anywhere blackout blind... All amazing!

Great product

Essential part of the nursery! Very easy for children to understand the concept and we now can't go away without it ( if we want to lie in past 5.30am!)
The book is a bit naff and I don't feel it adds anything to the product. But overall - we wouldn't be without our Groclock.

Best thing I ever bought

I bought this after many early mornings with my 3 year old son coming in at 4am saying its morning as he could see a little bit of light outside!!
It only took about 3 days before he didn't come out of his room until the sun came up on his clock with a big grin on his face being very proud of himself saying the sun is up mummy.
Even now when he wakes up he will stay in his room until the sun comes up :)
His 2 year old brother is learning it now too as they are in the same room so this is the best thing I have ever bought for the nursery.

grow clock

Love this product's my son loves to set it his self and watch the sun go down . He always stays in his room till the sun shine comes up works a treat and gives him a sense of time with out us having to yell him, as how many stars are left is how long he has to stay in bed . Plus the light from the clock gives him just enough to not be in the dark and makes him feel safe


This clock has changed our lives!!! I would recommend to all parents with an early riser. My little boy has been completely and utterly trained by this clock for the past year and a half. He will not leave his room until his 'sun' comes up. I had no idea whether this would work and just how we would make him wait but he does and we take it everywhere we go!

A little bright but highly recommended. Fantastic product.
Samantha Colton

I love this clock having used it since my 5year old was 2 and moving into a big bed. He quickly cottoned onto it and it wouldn't cross his mind to get up before the sun came up. My only critique is that the backlight is too bright for us, even on its lowest setting. Nonetheless, I'm looking forward to introducing it to my daughter as she makes the same transition.


My 2.5 yr old for this for Christmas and within two nights he understood the blue stars for sleeping and yellow sun for waking up...I watched at his door this morning. 'Oh no blue stars..sleep" it then turned yellow....'Yay, Mummy it is yellow now, get up!' Highly recommend. It does take a little while to master the controls but I guess it has to be child proof!

recommend this

My son got this for Christmas. He loves that he can turn on the night function. He understands that the sun means wakeup time and the stars mean sleep. I have not locked it yet as he enjoys Being able to change the face. He so got the alien face which he loves very much.

Good product but too bright

This works really well, and would get five stars but for the brightness. It is too bright even on the 1/10 brightness setting. Why did they make them so bright?

Great idea!

I bought this for my son and although he is too little at the moment to understand time he likes the happy faces of the sun and star. Getting him familiar with it early on will help him later. I really like this it is easy to use and set up.

Couldn't be without it!!!

We first bought our Gro-clock when my oldest son (now four) moved into a bed and began getting up agonisingly early. It took less than a week for him to the get the idea and since then we haven't looked back! It is lovely as it's incorporated into the bed routine with my boys saying "na'night sunshine" before I press the button every night and it is there throughout the night as comfort and a small amount of light. I now have another son (now two) who has grown up with the clock as part of his routine and they both come into our bedroom in the morning with the same phrase "the sunshine's out mummy" (which is always nice to hear). I honestly can't imagine life without it! Thank you gro!!!!!! :)

Great idea

We decided to get this for our son as he was deciding that 5.30am was a good wake up time! We really trust the Gro products having used the Gro Egg and Gro bags and thought we would give it a go. The clock and book are very good quality, we explained carefully to our 2 year old the idea of the clock and waiting until the sun came up before he got up, it took a couple of nights and it was a complete change for us all. My son loves the idea of having his own clock and says Good Morning Mr Sunshine in the morning (morning being a time we select rather than him!!!) I cannot recommend this enough, you may think it won't work, but give it a go you will be surprised and all of you will be rested!! A happy household :-)

Great idea although setting a bit fiddle initially
Lulu locket

This is a fab clock that our eldest has called her special clock, she loves the features and says the sun has legs when she loons at the rays.

The setting of the clocks alarms was really confusing I found but through trial and error managed to finally set the wake up a the correct tine . I found the wording along with the symbols a bit contradictory really.


My son had sleep issues ever since he was born--he would cry himself to sleep, wake up throughout the night, didn't know when it was morning, had short naps, experienced sleep inertia, etc. I was waking up with him at 5am every morning. We bought this clock when he turned two years old and trained him to sleep progressively until 7:15. After all the things we tried previously, I could not believe the results we experienced with this clock! Amazing! It totally transformed his sleeping habits, and I am so thankful! We've been using it for a year now, and my son wakes consistently every day at 7:15 and exclaims excitedly, "My sun's awake, my sun's awake! Come see it!" Easy to understand. Worth every penny and so much more. I plan on buying another for my one-year-old.

Wonderful Invention

I recently bought my 2year old the groclock after he began to wake before 5am. It's early days & he still wakes but he stays in his little bed till the sunshine comes out! He really enjoys saying goodnight to the sunshine & hello to the stars. I think this has to be the best thing that I have ever bought. A WONDERFUL invention! Thank you

Amazing but needs something improving

There is a review by someone called Matt that sums it up for me. Amazing clock but without be being able to add batteries is limited. I was really hoping to take it away with us camping as but it needs mains. Still very pleased I got this tho as it has made a drastic difference to our life. Just worrying that the time away from it may undo all the hard work.

Lovely, well built product that is easy to use

The accompanying book is a great idea, giving meaning to the clock.

My son loves saying goodnight to the sun and hello to the star. He can also switch it to night mode himself at 3 years old.

He fully understands the clock and will stay in his room until the clock is yellow so it is working as expected in the mornings.

Downsides: I was expecting to be able to time the sunset also. Our biggest issue is not early mornings but late nights. If the clock went blue by itself at a set time then I could use that to get my son to stay in his bed. As it is you have to change it to blue yourself meaning it only solves half the problem. Had I understood this I probably would not have bought it. Second issue is the brightness. Even on the lowest setting my sons room is so light at night that he can move around, read his books and keep himself awake. As a result his late nights got later making the problem worse not better. We have now set the brightness to be off so there is no light at all. This works better but it seems a shame. I cannot understand why it would need to be so bright. The brightest setting must be completely unusable.

I am glad we have the clock, to avoid those few early wake up calls but I feel there is the potential of a mark-II version with some other options to assist with different sleep issues.

So Helpful

We bought this for our son a year ago when he was 2yo to teach him when it was ok for him to get out of bed without having to call us. He now uses it to know when he's allowed out of bed if he wakes early. This has been a fantastic product for us, and we highly recommend it.

Good product, but ...

Although this is a good product, and works really well at night, I think a few software changes would make it fantastic. It would be more useful if you could set the duration of day time nap, rather than having a fixed wake-up time. My toddler sleeps when he is tired, so I have to constantly reset the waking time. I think it would also be useful if it had an analogue clock time for when he is a little older, rather than a digital clock. Concept great, just needs a little more modification.

Great but could be improved

Overall, this is a great (if not pricey) product which does a great job of teaching young children when it is the 'appropriate' time to get up. My 2yr old son adapted to it within a few days and is now makes a point of showing how the 'sun has come up' each morning. He does still sometime ignore the clock though, and get up before the sun.

My only real criticism about the clock is the fact it does not have any form of battery back-up. The clock therefore switches off as soon as power is lost and the time has to be reset once it is restored. I haven't read every previous review but no-one seems to have mentioned that the 'key lock' is kind of pointless when children can simply pull out the power lead from the back as my son has done! I have had to move it out of his reach for this reason.

Having a battery back up is no-brainer as far I can see, particularly since it is LED powered and therefore has low power consumption so any battery should last for ages.

No more night wakings!!

I cannot say enough good things about this product. My son was a VERY bad sleeper. It took him up to an hour at night to stay in bed and sleep and he used to wake up frequently during the night crying. When the days got shorter he'd wake us up as soon as 5:00 a.m. and there was no way to get him back to bed. NOTHING worked, no sleep-training, lullabies, darkening the window...

It took him as little as three nights to develop a good sleeping habit with the gro clock. It is worth every penny! We've been using it for about a year and a half (he was about 26 months old when we bought it).

Good, but could there be a remote control one?

My 2 year old has been using it for 6 months. She knows exactly how it works, but chooses to ignore it sometimes. Rather than have ages of tears, a remote control would allow me to change the status of the clock from outside her room. That would mean day could arrive earlier, if I wanted it too!


i bought the clock a couple of years ago for my 4 year old and it works it takes time tho.. i now need to buy anoher one as my 3 year old son needs one and the eldest doesnt want to give it up

Fantastic product

I started using the gro-clock when my son was only 15months old so this can be used a lot earlier than 2yrs. He was a bit too young to understand the story so instead I developed my own routine to introduce the clock - with a few days it was working!!

I now take this on holiday with me too so my son can quickly adjust to new time zones......absolutely amazing product. I would highly recommend it!!

Toddler Best Buy

Cannot recommend enough. First night results! Think our hype about her special new clock and the story helped and we did have a settling in period where she would wake early and need us to go in and remind her to wait until the sun comes up. Love the 2 settings (we have 7am weekdays and 7.30 weekends)! So much better than Cars clock we bought for son as it didn't have the proper time and went through batteries like no tomorrow and made a scary sound when it went off waking him with a start and worse still when batteries ran out in the middle of the night it woke him up! Will buy a Gro Clock for the next friend to have a baby for sure.

Fab. works a treat after a few weeks!

I got this clock as my son was waking up at 6am, it didn't work immediately but after a few weeks of us waiting in his bed until the sun came up he got it and now wakes up and shouts 'the suns come up!' Would recommend for 2yrs +

Why didn't I buy one sooner?!?

This clock is amazing. I took me a while to order one as it isn't cheap for a clock but now I am so glad I did. My son now stays in bed until the sun comes out (and sometimes later!), which gives him two very happy parents. And the book that accompanies the clock is excellent. Worth every penny. Fantastic. Thank you!

Fantastic Product

This clock is amazing! Exactly what I was looking for. It shows the time for adults as well as showing a basic difference between sleep time and wake time for a child. I recommend this highly!


I bought this clock around a year ago when my daughter moved into a bed and discovered she could get out and would wake quite early and up she would get. Love the book that comes with it as it explains how the clock works. My daughter was able to tell the story not long after I got the clock and knows that she can't get up until the sun.

fantastic, amazing, 100%successful product!!!!

had been thinking about buying this product for some time but wasn't sure if it was just an expensive gimmick. how wrong could i be. our 2 1/2yr old has always been an early riser and 7am is a lie in. however after months of waking at 6am or sometimes before i took action and ordered the clock. hallelujah!! within a week she was telling everyone about her new clock and had to do 'show and tell'. we started with 6.30am starts as recommended by a previous reviewer so she wouldnt get disheartened and are already up to 7am with her sleepinng past that on several mornings. 100%recommend this product. well done gro group.

Life Saver

A total life saver! I wish we'd found this product ages ago - perhaps then we could of had more sleep. So simple, yet so effective. I recommend this clock to all of my friends with young kids.


Superb! such a great invention. My little one particularly likes the beautifully illustrated book that comes with it.

Done it again!

The people at Gro have done it again! This is the best invention since the Grobag! The Grobag gave us all that sleep for the first 3 years, and now the Gro-clock has taken over the baton, keeping our little one in bed "until the sun". The book's fab too. Thanks again for a wonderful product. I'm recommending it to all my friends.

Christmas Bliss

It even worked on Christmas Day! What more can you ask!

Even for older children

I purchased this product in the hope that my partners 6 year old, who although lovely, would wake us up at 5am everyday, might be pursuaded to stay in her room or watch CBBies until the 'sun' comes up - and am delighted to report that it works brilliantly! The bags under my eyes are subsiding daily. I highly recommend this product, even for slightly older children!

Give it time

FANTASTIC - but give it time ! Started this clock on my 2 yr 1 week old little boy, who woke us up anything from 4.30 am ! At first nothing happened although he loved having a clock by his bed and watching the moon go to sleep. After a week we ended up setting the time so that the sun came on before he woke, to give him the confidence the sun would come. We then changed the time by 20 mins and again for a week he woke up after the sun ! Changed the time again by 10 mins and if he wakes up and sees the moon he goes back to sleep ! He is so proud and happy when he wakes up and sees the sun and shouts, time to wake up ! Really does work, just dont expect it to work the first night, fantastic product, would highly highly reccommend ! Thank you !

my sun has come up

We bought this for our son for his 4th birthday, despite my husband's scepticism that he was too old for it. After a coupe of weeks he had got the idea and now consistently stays in his room until "my sun has come up, Mummy." No more shouting "Can I get up yet?!" to wake his little sister. He adores the sun on the clock and his sister (21m) is jealous of the clock. I think we are going to need another. The digital feature on the new version would be fab.


This clock and book are an excellent purchase, superb quality and worth the money. I bought this for my son who is nearly 2 about 6 weeks ago, he absolutely loves saying "bye bye sun, good night star" every night and it is now part of his bedtime routine, however he seems to take no notice in the morning and gets up when he wants sometimes before before the sun, sometimes after, hence the 4 star rating. I'm hoping as he gets older it will work for him if we keep pushing it. That said, a great product he loves it and the book.


This is one of the best things I have bought, and I recommend it to all my friends. Our 3 year old was waking up very early, and we realised it was because he was genuinely confused about the time, particularly over the summer with the very light mornings. We got the Moon/Sun clock, and each night he loves saying goodbye to the sun and telling it what he has done that day. He always waits for the sun in the morning before getting up now. I also give him a sticker for his reward chart every morning that he waits for the sun, as an added incentive! Great idea and worth every single penny!

Love this

We love this clock, our daughter stays in her room until the sun comes up even if she has been awake for ages! We have the older version with the moon rather than the star. I'm not sure why you have changed it, it makes more sense to be a moon and the sun surely? Bit disappointed on that as we want to buy one for our youngest daughter! Either way it is a great product!


Fantastic product. My girls were getting up from 5.30am onwards to check if it was 'wakey time'. Since introducing this clock they stay in bed until the sun comes up. They love their clocks. I must admit I do find them on the expensive side. Especially when I had to buy two as they've a bedroom each.
