While Saturday Night Live has poked fun at the roly-poly baby with a commercial for “Baby Spanx,” there can be a serious side to newborns who weigh more than average. Unlike a bowl of Italian pasta or a Texan’s ten-gallon hat, bigger isn’t necessarily better when it comes to babies. There’s even a name for infants too big to be born vaginally: macrosomia. And larger-than-average newborns can be the result of gestational diabetes in the mother. Expectant moms with gestational diabetes can give birth to babies whose bodies produce more insulin, which can cause low blood sugar and breathing problems.
