Ideas on how to teach ds it's not okay!

[knackered76]

My ds has just turned 4. Today I had to speak to the head of the pre school he is at as he had thrown some lego at someone deliberately. He had also pushed someone off their chair with his foot. Recently this kind of behaviour has been increasing at home and apparently at school :( I'm 5 months pregnant and wondering if it's something to do with that. When I talk to him about his behaviour he often gives me his death stare and nothing appears to get through. How do I make him see it's not okay to act like this? I also have a dd (5) who has begun to recently think being physical is the answer to everything that annoys her!!!!!

What does he love doing/playing with? For my DS is is riding his bike to school. We had a few problems earlier this term with him not listening to teachers, starting to answer back etc. He had to walk to school for a week - seems to have focused his mind, he has behaved well and continued to do so since getting the bike back. He has had lots of praise from teacher and us for being so well behaved and tbh I think he is actually enjoying school more as a result so that has helped sustain it (so far...don't want to tempt fate).

Apparently boys do get a testosterone surge around 4/5 which makes them much more aggressive and physical, I find lots of outdoor exercise is the best cure for that . It is also of course possible that this is a bit of attention seeking due to sensing new baby's arrival but I think more likely typical boy stuff.

At home if DS gets physical with his younger sister it is straight to his room until he calms down and apologises as first response (zero tolerance!) and then removal of other privileges (time playing on my phone/lego taken away/no TV of his choice and of course the bike again) if it continues. Be consistent and stay calm throughout - the message will get through that it is not ok to hurt others.
