Does parents birth weight predict baby birth weight?
A father’s genetic code influences the weight of a baby at birth, according to a new study led by the UCL Institute of Child Health (ICH).
What determines your baby’s 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.
Does your weight affect the size of your baby?
For weight gained from 14-18 weeks, birth weight rose by 26.1 grams for each additional kilogram of maternal weight gain. But weight gain later in pregnancy had no effect on newborn size. Early in pregnancy, the authors note, the fetus grows slowly, so weight gain mainly involves the mother’s body.
How does low birth weight affect a newborn?
A baby with low birthweight may be at increased risk for complications. The baby’s tiny body is not as strong and he or she may have a harder time eating, gaining weight, and fighting infection. Because they have so little body fat, low birthweight babies often have difficulty staying warm in normal temperatures.
How is baby’s weight determined by ultrasound?
Ultrasound uses volumes to calculate fetal weight. It takes measurements of the head, waist circumference and some bones and comes up with an estimate. But it can’t measure the density of the fetal tissues directly.

What causes a big baby?
Genetic factors and maternal conditions such as obesity or diabetes can cause fetal macrosomia. Rarely, a baby might have a medical condition that makes him or her grow faster and larger. Sometimes it’s unknown what causes a baby to be larger than average.
