Baby is overweight at 36 weeks

Erika

My ob said my baby weighs 3373 grams at 36 weeks which is too heavy for his age of gestation. Ob said I should prepare myself for a c section but me and my husband prefers normal delivery since a c section in our hospital is expensive. As a financially struggling mother, I’m very sad. Any tips or advise? Can i still diet to slow down baby’s weight?
