Baby 1 of my bumper is from aussino, it's part of the bedding set i bot during their sale, $40 plus, comes with bumper, bedsheets, pillow, comforter. think for the first 3 months would be using the bedsheet and bumper since not buying a pillow for bb initially.
i also bot another bumper set from ikea, $35, polka dots design but that one, is quite thin.
