At what age did you remove the crib from the baby's room and replace it with a toddler bed? My 2 1\2 year old son just got big enough to climb out of the crib and crash to the floor. We had been talking about getting him a bed for a while and before we got the chance to go shopping for one, in the middle of the night our son starts crying and wakes us from a dead sleep walking out of his bedroom. I freaked out and thought he was hurt. Has anybody else had this happen?
