My wife thought that, in order to give birth, the woman would have her head cut off, and the doctor would sew it on after the delivery. Since the neck was the only "hole" that would be large enough to pass a baby through, this seemed to make sense to her.
A childhood belief about giving birth

others believed things like this
- I used to think that to give birth, a woman had a slit cut into her inner thigh, and the baby would come out.Anon

— Tasha K - Until I was five, I used to think that women gave birth to baby girls and men gave birth to baby boys— Cassidy K
- I thought that to breastfeed, a woman had to poke a hole in her nipple (like the hole in a bottle nipple).— Imani B.
- That to make a baby a man (over 21 & under 25) had to kiss a woman (over 19 & under 21).— Johny
