i think i know what u mean. DN is now starting to pull himself up, so he pulls WHATEVER he can grab... so that means his bumper la! so when he's in the cot after 3 mins, the bumper is squashed into the mattress. -_-
have u tried tying the bumper to the top of the rail on the cot? that way, he can't possibly pull it down. if u tie it to the sides, he can pull it down. but this only works if the side of hte cot is real low lor.
