After refusing a planned cesarean for suspected
macrosomia based on a 38 week ultrasound estimate of fetal weight, she gave birth vaginally to a healthy baby and later found that the midwives model of care better met her needs
as a pregnant woman.
Although labor arrest and abnormal or indeterminate fetal heart rate tracing are the most common indications for primary cesarean delivery, less common indications ---- such

macrosomia, multiple gestation, and maternal infection (eg, herpes simplex virus)---- account for tens of thousands of cesarean deliveries in the United States annually.
Care providers are concerned about vaginal birth for a potential «big» baby (fetal
macrosomia) because
as fetal birth weight increases so do the risks for shoulder dystocia, vaginal tears, and permanent nerve injury to the newborn.

as maternal conditions, such
as obesity or diabetes.

Regarding the child, the importance of the intrauterine and early postnatal environments for metabolic programming and modifications of the epigenome is increasingly recognised, 12 — 14 particularly for metabolic diseases such
as obesity and diabetes.15 Thus, GDM is related to
macrosomia at birth (> 4 kg), to excess body fat and (central) obesity and to insulin secretion in infants and children, the obesity being in part mediated by maternal body mass index (BMI) or birth weight.16 — 23 Intrauterine exposure to GDM also doubles the risk for subsequent type 2 diabetes in offspring compared with offspring of mothers with a high genetic predisposition for type 2 diabetes, but with normal glucose tolerance during the index pregnancy.24 Maternal prepregnancy overweight and excessive gestational weight gain also predict high birth weight and adiposity during infancy.12 25 This is highly relevant,
as up to 60 % — 70 % of women with GDM are overweight or obese before pregnancy.26 Finally, maternal lifestyle behaviour such
as a high fat diet or lack of physical activity during pregnancy can influence offspring adiposity independent of maternal obesity.12 27
