A multidisciplinary clinic that includes an endocrinologist, maternal-fetal medicine specialist, dietitian, and certified diabetes educator (CDE) will manage study participants. They will be seen monthly or more frequently as needed by the physicians. The participants’ weight and blood pressure will be recorded at each visit, along with routine obstetric care evaluations. Baseline and 34-week HbA1c will be recorded. The neonatologist will manage infants postnatally and assist mothers with breastfeeding.
