2yr old and pregnant

Ese

My two year old is always all over my tummy, he just wants to put his head on my tummy always, I like the facts that he's getting close/connected with the pregnancy but every time he does that he just bang my tummy and sometimes I feel the hurt. I don't know what to do to stop him and I hope the baby is ok.

My first scan is this Friday and I pray everything is fine, I'm not feeling any symptoms just lower abdominal pain & cramps on and off..

Any advice..?
