DS is 3 on Sunday and his behaviour is just getting ridiculous. We don't know what else to do.
He bites, slaps, smacks, pushes his younger brother over.
Grabs food off plates and throws it on the floor. Throws his food around the room for fun.
We'd say no to something 10 times and he won't listen.
He sits on my head, on his brother.
Can get very hyper and over excited which mostly leads to biting etc
He laughs if we shout at him to stop. We put him in his room when naughty, but he's actually enjoying being in there. And usually both of those attempts lead to him doing the same behaviour again anyway.
Is this normal behaviour for that age? If so what do I do about it? We're very lost
