My 2 year old son (29 months) has climbed out of his crib two mornings in a row now when he is done sleeping. Need advice on when and how to transition to a toddler bed.

He has for a long while now had the ability to climb out, he just has not fully executed on it. Now he's freaking cavalier about it.My wife and I are a bit concerned about him being groggy and falling on the way down, so we are toying with the idea of transitioning him to a toddler bed.He has a nice collection of toys and books in his room and I am concerned that he will "take advantage" of his ability to easily get in and out of the bed.Lastly, he has been in his crib since he was ~6 weeks old, so there is some concern about his comfort in losing the "cage" that is a crib.Any words of advice are appreciated.Thanks! via /r/Parenting http://ift.tt/2vF6Gs8
