I've used bumpers with my son he's almost a year old and I've had zero problems. Ever family is different. I survived with bumpers and I kid and my son is too. Good luck!
Toys r us has them called go safe alternative bumpers. I googled individual bumper pad for crib. Bed bath, toys r us, Amazon, buy buy baby and Wal-Mart carry them for $10 a package.
