Are small babies hereditary?

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.

What causes having a small baby?

The most common reason why a baby is smaller than average — weighing less than 2.5kg at birth — is prematurity (being born before 37 weeks' gestation). The earlier the baby is born, the smaller they are likely to be. This is because the baby will have had less time in the womb to grow.

Which parent determines birth weight?

A child inherits half their genes from their mother and half from their father, and the child's own resulting genetic make-up plays a role in birth weight. The paper reveals the complex balance of how both the mother's genes and the baby's genes can influence the baby's growth.
