Do genetics determine baby’s size?

The findings suggest that genes inherited from the mother and father regulate a baby’s growth at different times during the pregnancy, to ensure a successful birth as well as the mother’s survival. Fetal growth is an important area of research which takes into account the future health of babies.

Doctors determine their estimate of fetal size based on how big your belly measures. If it measures large for dates, they figure it’s going to be a big one.
