Question, I'm trying to explain to my 3 year old that I'm having a baby. And baby is in mommy tummy. Every time I tell him he say no mommy no baby in your tummy. It's a little funny to me because he is so serious but I don't know if I'm delivering it wrong or not being serious enough. Not sure if he don't understand or not. Can some other mommies give me advice on how to better explain it to him. I don't want him to be too shock when the baby comes. Please and thank you mommies
