I know some teasing is normal but my son will relentlessly tease his sisters all day long. I’ve asked him nicely to stop, I’ve disciplined but nothing changes. I’m finding the screeching and screaming all day difficult to deal with as I don’t get a break from them anyway and it’s all day long. Maybe I need to get better at ignoring it as I’ve been told before that it’s normal. How do other parents cope with this?
