Being a paranoid mom, i never bothered with crib bumpers when setting up the nursery. It didn't matter in the end since she didn't even move when swaddled. LO is almost 7 months and will sometimes bang her head or get arms/legs caught between the railings. Last night she was sitting up in the crib and banged her head when she fell down.

Should i get a crib bumper (despite the fact that they are discouraged) or just accept that LO's head is going to get banged up once in a while?
