My brother used to flick himself in the head when he would drink his sippy cup as a relaxing tick…. He obviously outgrew this. My husband used to bang his head in the crib as he was falling asleep, he still does this to this day occasionally to relax. Walk in to him dozing off and he’s banging his head into his pillow at 31 years old 🤣
My daughter smacks herself in the face.
My daughter likes to hit her head on the wall because its apparently “funny”
My son used to do that for fun when he was young , he also used to pull his hairs but when we asked his pediatrician, she said its his way to sooth himself. So over time he forgot doing it, but i can understand your concern . Talk to your pediatrician
