Ds is 22mo and sleeps in a travel cot, with a cot mattress in it. He hasn't attempted to climb out yet, but a lot of family/friends' dc of similar age sleeping in normal cots have already started climbing out of them. I'm dreading it as I want to keep him in the cot as long as possible, and only put him in a bed when he is a lot less likely to roll off, but obviously climbing out of the cot is more dangerous than falling out of bed.
Anyone got any ideas whether it is possible for toddlers to climb out of a travel cot (as it's mesh as opposed to bars) and what age they started doing it?
NB. My concerns re a bed aren't because I'm overprotective - he has haemophilia so falling out of bed will mean serious injury for him.
