it's an interesting article because young children who do not yet know how to read time have trouble knowing if when he woke up it is time to get up, since he was in the Kid'Sleep her room, our 3 year old son not just in our room at dawn, he waits 7:30 (time we chose) by cons I find it unfortunate that the time is displayed in a small screen which in addition is not back-lighting, I thought when it would be great, it could serve as a clock but that is not the case, if I had known, I would have bought as compact travel Kid'Sleep.
