I want to keep my girl in her crib as long as possible. But my 22 month old is just starting to put her foot up on the top of her crib rail. When you noticed your baby doing this, when did you transfer her/him to a toddler bed? Do I wait for her to actually climb/fall out? Is it possible for this "leg up" thing to be just a phase and she will stop doing it soon? Please let me know what you did when you saw your baby showing signs of climbing out of the crib. Thanks!
