Kids can sense it

So we told my two year old son about us having another baby and explained to him it’s in my belly. He may not fully understand but every day he gives the “baby” a hug and kiss through my belly. (Super cute) well we started asking him if it was a girl or boy and every single time he says girl. No matter how we word it, which one we put first... he always says girl. I don’t find out until December and I am dying to know if my son is right. I’ll be happy either way just for a healthy baby after my two miscarriages last year, but I would kill for a baby girl 😍 what are some of your stories where your other kids could sense the right gender or that you were pregnant before you knew?
