that's how my baby girl is kind of she has mixed feelings

My 2 year old (almost 3) is in denial. He refuses to believe that there's a baby in my belly and I'm almost 36 weeks pregnant. I tell him everyday "there's a baby in my belly" and he says no. I'll ask him if he's having a sis or bro(we don't know the gender) and he says no baby. He's very, very attached to me so will see how he reacts when the baby is here.
