Making healthy choices during pregnancy will assistance ensure that your babe is not born too modest or as well big. Smoking during pregnancy increases the risk of a low birth weight baby, as does malnutrition.
Gestational diabetes or otherwise gaining excessive weight during pregnancy increases the adventure of a babe being born larger than normal.
