I have a 3.5 year old boy and a nearly 1 year old girl, and boy is totally feral at the moment. Hasn’t really recovered since arrival of baby sister, plus split with partner when baby was 9 weeks old. He has had so much change bless him and he is only a month in to living over two houses. But his behaviour is so challenging at times - very rough with little sister, lots of tantrums, very hitty, very unsafe to take out. But and angel at preschool 🤨 is this normal for little boys?!?!?
