My son is 2.5years old and seems to be getting very physical. I wouldn't call it aggressive, but my pregnant brain can't think of the right word.

He loves to jump (on to you), punch, kick (not out of anger, in a play fighting way), push, and wants you to do them to him. He loves rough and tumble play. He loves to destroy. His Lego isn't used for building now, it is used to throw across the room with noise effects.

My first was a girl, and while she was physically aggressive in an angry and violent manner (unleashing her huge amounts if anger, often) my son seems to be doing it in what he thinks is a "fun" way. So feels entirely different.

My younger brother was 6 years younger than me, so was mostly at school when he was this age, so don't remember him being like this at all. My partner is the youngest, so doesn't know if he was or his brothers were like this at this age.

Can anyone shed some light? Is this normal? I try to explain that it hurts, but he seems to still think it's fun. Maybe because his sister usually hurts him in anger then tried to palm it off as just a game or something. I didn't think "testosterone surges" happened until around 4? Is this an early onset, or will things get even worse then?!

I'm starting to be a bit worried, as he tries to jump and rough and tumble with me, and I'm 9 weeks pregnant and worried he'll hurt my belly baby!
