We bought the Kidsleep when our older daughter was 2 year old and initially used it as a night light, after about 2 months, we then switch to day / night light. Our daughter adheres since the hare! When he wakes up she calls or is, when he is asleep, sleeping too, at least she keeps quiet. The Kidsleep's really a good help to show a child, when day and night is when. Very important when summer is and it's light already by 5 clock. Likewise, of course, in the winter when it is still dark even at 7:30 clock. We have him now for 3 1/2 years. Recently, it is needed for our youngest, so she gets now a stand-up rabbit for Christmas :-)
