I have a 2 year old son and I haven't told him till today that he's gonna have a little brother or sister but before I told him he would rub my tummy and put his head on it sometimes and I don't have a noticeable belly so I'm just wondering if he already knew that their was someone in their lol have you ladies experienced this ?Â
