We currently don't have any as LO loves to sleep right up against the sides of the crib. My concern is he will sleep right against it and not be able to breath. My other concern though is right now he moves around a lot and is constantly hitting his head against the sides of the crib. Sometimes it's hard enough that I hear it and it wakes me up. I'm worried he will have damage to his brain or something with constantly hitting his head.
We've tried the mesh bumpers and they didn't really help.
Should I worry about any damage he might be doing?
