Query: Didn't Last One Day

I purchased these thinking that with the adhesive they would stay on the crib. Well I was wrong, in the morning when I went to get my son, he had already taken one end of the crib rail off and was working on chewing underneath. I think with the slobber, the adhesive gets wet and does not adhere. I wouldn't waste my money on these. I have ended up purchasing fabric protectors with ties, to see if they work better.
