Hello ? Do your babies hit their heads when they sleep and want to lie down more comfortably in the crib? We have a problem, it lies in the corner of the crib and starts hitting its head against the wall, we hung side supports but it's useless! It softens the blow but still hurts, I don't know what to do so that he doesn't hit his head.
