DS is still in his crib. Thankfully he has yet to climb out at all, so it hasn't been an issue.
On the other hand, I think he is getting close to ready for potty training and I feel that a toddler bed would be better for that, since he'd be able to get in and out himself.
Where are you guys at on this? Still in a crib, if you switched, when did you do it? How did it go? Any major challenges?
