Question- does anyone else have a little head banger on their hands? My 12 wk old thrashes around the crib a ton. He wiggles all over the place and sometimes thrashes around pretty hard. Tonight he hit his head on the back wall of crib and it made a little spot on his head. 😢 but worried about putting the bumper back in because of all the controversy over it, but also don't want him to keep hitting his head hard. Anyone else dealing with this?
