I think there are 2 issues with bumpers
1) baby can get their face wedged in it and suffocate- with a very young baby they can't move around much so if you put them down in the middle of thr bassinet they'll stay there
2) it limits the flow of air around the baby - but why that shouldnt be a problem with a bassinet I have no idea, maybe because its not so deep?
