Rated 4.8 out of 5 by 44 reviewers.
Rated 5 out of 5 by Great product Bought this for my 2year old daughter as when the light mornings started we got regular 6am wake up calls, thought this clock was worth ago and I am so pleased i bought it. First morning we set it she has stayed in her bedroom till the sunshine has appeared, thought it would take some getting used to but she's took to it from day 1. Worth every penny, would highly recommend!! 09 May 2013
Rated 5 out of 5 by Brilliant little clock I purchased this clock for my 2.5yr old daughter as she started waking up earlier and earlier each morning and asking if it was morning time yet! Now there is no confusion what time it is and when it is time to get up :) comes with a lovely little story book to help teach your child morning time and night time. Fab product wish i'd discovered it sooner!! 06 February 2013
Rated 4 out of 5 by good idea My daughter loves having the story read to her and has got the idea that the sun comes up and its day time and when the stars come out its bedtime had a few problems with the picture not changing at the right time but apart from that brilliant product 30 January 2013
Rated 4 out of 5 by Great buy Our two year old boy has always woken up between 5am and 6am. He finally believes us now when we tell him it's not morning yet!! That's priceless! 28 February 2012
Rated 5 out of 5 by Best purchase i've ever made. After two and a half years of broken sleep we thought lets give this a go. And im so glad we did. We are now getting full nights sleeps its great. Our daughter picked up the idea really quickly, understanding that when the stars are out she must stay in bed. She loves waiting to see "mr sun" wink and go to sleep. And comes through in the morning saying the sun's come up mam. The book is lovely also. 24 February 2012
Rated 5 out of 5 by Quality purchase This item is easy to use and versatile as a clock and night light. I like the features ie yellow suns for daytime and blue starts for night and the way the stars countdown as the yellow appears. My son is fascinated with it. :-) 23 February 2012
Rated 5 out of 5 by Brilliant We purchased this clock when our 14 month old son started waking at 5:15 and not wanting to go back to sleep. Although it is recommended for children 2 years+, we thought we would give it a go. The concept of the clock is so easy and visually clear and interesting, that at 14 months, he is already grasping it. The clock gives a visual representation of time and our little boy now waves to the sun when he appears, which is very cute. Whilst we still haven''t quite cracked sleeping through the night, the clock gives us something to use to symbolize our message about not getting up yet, and with perseverance it is starting to work. The actual clock itself is very neat, clean and attractive to look at and I am very glad we have invested in it! 17 February 2012
Rated 5 out of 5 by Briiliant idea 3 year old grand daughter has now learnt to stay in bed until the sun comes out and actually told daddy off for getting her up when the stars were still on. Great idea 16 February 2012
