I think it depends on the size of the kid too, but I would think it would look funny to see Emmy in a crib at 2.5 yo when she was was at least 37" tall. But my cousin is 2.5 now and only 24 lbs and 31" and it looks perfectly normal seeing her in a crib.

the farking nest ate my answer making m update my info again... really, it's a way to trick us in to getting their stupid newsletters, i swear
anyway, i would say 3.5-4. if they are old enough to be in real pre-k, then they are old enough to be in a bed.
