Ds is just about to turn 3 and currently sleeps quite happily in his cotbed with sides removed. Wasn't planning to get him another bed for ages but we have been offered a second hand midi sleeper for free from a neighbour. I like the idea that could store lots of toys under it or even make it into a little den. My only concern is whether it is too high? I think he will be just fine and would easily be able to get in and out by himself. Dh however is worried he might fall when half asleep if he gets up for a wee or something. Anyone else got this type of bed for their 3 year old?
