Crib bumpers.

mamaX2

My daughter had a breathable crib bumper on her crib. Well recently she's become aware of it and has started to pull on it and push on it. So much so half of it is either tucked to the side of the mattress or she loosens it from pulling on it and has undone the Velcro that keeps it one attached piece. Is 9 months to young to take the number off?
