Is birthweight affected more by the mother or the father?

Question

My first two children weight 9 lbs, and 9 lbs. 13 oz., respectively. This is my third child, but with a new father. I am divorced, and so is he. He has two children who both weighed under 7 lbs. I'm curious if the new baby is more likely to be big because I make big babies, or if it will be small because He makes small babies. Does this make sense? If not I'll add details. Thanks.

Answer 1

My doctor told me that I would most likely have a smaller baby because I was a small baby but who knows, I will find out in a few weeks.

Answer 2

There are a variety of factors involved, so it's hard to guestimate. My baby weighed 7# 11 oz at birth, I was a nine pound baby and her daddy was a 10+ lb. baby. The ultrasound said she was 9 lbs 10 oz so they went in and got her out by c-section. I had gestational diabetes, that can contribute to a larger baby, but I did smoke occasionally while pregnant. My boyfriends ex is heavier than me, but not by a lot, and his first daughter was over 9 lbs. And I had a horrible diet while pregnant, no appetite the last two months, so I ate maybe once a day and took vitamins. I bet your baby will be in the 8 lb. range, right in the middle. Good luck!

Answer 3

Baby's birthweight does not depend on the weight or size of the mother or father. It depends on the food intake and daily activities of the mother while carrying the baby. The more you eat and less exercise, the bigger and heavier the baby will be. That's what my doctor told me when I was still pregnant.

Answer 4

I read that it usually goes by how big the mother was when she was born. But every baby is of cause different.
