Is baby birth size genetic?
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.
What determines the size of a baby?
Led by Dr Gerard Nahum, the team studied 244 healthy Caucasian women giving birth to full-term single babies. They used factors known to affect foetal size, such as sex, the mother’s height, starting weight and weight gain in the third trimester, plus the father’s height.

What if fetal age is more than gestational age?
Babies are called large for gestational age if they weigh more than expected for their gestational age (weeks of pregnancy) at birth. Diabetes is the most common cause of babies who are large for gestational age. If a baby is too large to fit through the birth canal easily, delivery can be difficult.
