Low blood sugar in newborns is common and if prolonged or untreated may place them at increased risk for later learning and behavior challenges. Currently, we measure newborn glucose with at least four painful heel sticks, missing one in four episodes of low blood sugar. The goal of this observational study is to develop a less invasive approach to glucose monitoring, developed for newborns, that provides more frequent glucose measurements. We will also measure how a pregnant woman's health impacts newborn glucose, and how newborn glucose is linked to brain oxygen saturation and development.

Macrosomia is associated with increased risks for both the mother and the baby, including complications during delivery, injuries, and even death. The accurate diagnosis of macrosomia is often difficult before birth. There are a number of factors that can increase the risk of macrosomia, such as maternal obesity, diabetes, and excessive weight gain during pregnancy. There are also a number of different techniques that can be used to try to predict macrosomia, but none of them are perfect. The aim of this study is to evaluate sensitivity of measuring fetal clavicle length in third trimester compared with biacromial diameter and Hadlock formula IV for prediction of fetal macrosomia.
