I don't remember where I thought babies came from, but I have distinct memories of when I was about 5 and some kids in nursery school were playing with dolls, pretending the doll was havin a baby and they were doctors. They apparently thought all babies were born by caesarian section - one of the boys pretended to sew the doll up and another kid said "James, you forgot to take the baby out!"
