My daughter keeps trying to bite us and on occasion, succeeding. I'm a SAHM and no daycare or other child interaction. No idea where shes getting it from. She is constantly trying to bite us and she just laughs! I've tried scolding and time out. I've tried hand smacks, small but smacks. My mom suggested forehead flicks and my husband tried that too. I push her face away and she thinks it's a game. Sometimes she will just cuddle up to us then bite out of nowhere. Please help. Idk what to do. Shes leaving marks when she bites and its gotten to the point that I'm afraid for her to snuggle up to me.
