Is there a way of curbing undesirable behaviour in babies? I'm not talking about punishing obviously!!! I'm just not sure of how to react when my 8 month old is shrieking over and over and watching my face for a reaction. I'm currently trying to ignore him when he does it (look away or turn around for a few seconds, til he's stopped) but it doesn't seem to help and I can't think of another way because if I look shocked he grins, if I say "no!" he laughs etc
I'm not terribly bothered by the screaming usually but I do wonder if it bothers out neighbours (thin walls, INCREDIBLY LOUD boy)
He also has a habit of hitting and scratching hard, usually at my face. I know he isn't intending to hurt, but he's so heavy handed and strong he grabbed my lower lip and yanked it with his nails so hard he drew blood last week. I put him down and walked away (mainly to go inspect the damage in the mirror!)
Am I doing the right thing by ignoring/walking away/putting him down when he does not so nice things? Or should I be saying a firm "NO" or something so he knows he's done something wrong? I feel like it makes no difference, like he's probably too young to understand either way. (He's 8 months) What should I be doing, if anything?
