DS2 was 2 in march and he still has the sides up on his cot bed. He's climbed out once, months ago but hasn't done it since, mainly because I think it frightened him!
Anyway, DC3 is due December so I'm thinking we should get a move on and take the sides off pretty soon.
When did you take the sides off/move your little'un to a big bed and how did it go?
