Crib bumpers are pretty controversial these days. Some mom's have them, some don't. We had them in the beginning, but honestly we weren't using our crib for sleeping. It was more for a controlled place for tubby time. When we did start to use the crib for sleeping for our daughter, she would get her legs caught in the bars because we removed the bumpers. So we got this breathable bumper. This eliminates the risk of your child getting hurt by getting their leg or arm caught in between the bars, and its not thick like fabric. So its the best of both worlds. Our daughter is 13 months old now, and we still have this on our crib.
