Bought this for my 5 year old daughter who was constantly getting up between 5am and 6.30am everyday!!! Mummy and Daddy were not impressed!!! LOL. This clock has been a god send, as we now set the alarm for the time that we find acceptable for her to get out of bed, and she instantly realised that she has got to remain in bed until the little ballerina cow lights up! A great invention and I would highly recommend it to any sleep deprived parents out there!!!!
