Some people say that when pregnant, the belly of a boy is more pointed, while the belly of a girl is rounder.

This theory has recently been scientifically confirmed. Epidemiologists from the Harvard School of Public Health reported in the newly published "British Medical Journal" that pregnant women with male fetuses eat more food during pregnancy than pregnant women with female fetuses. This is because male babies have greater energy needs than female babies, so male babies are born larger than female babies.
