So this past week, my baby boy (~9.5mo) has been slapping me in the face or scratching at my face or pulling my hair. He doesn't really do it to anyone else, not even my husband. It's kind of hurting my feelings, but I know he probably doesn't know what he's doing. Anyone else experiencing that? What should I do about it? I've tried saying "no" firmly, but he just does it again. Also, it's unpredictable bc sometimes he will kiss me but other times he will slap / scratch me.
