My kids were huge...DD: 9 lbs, 2 oz and DS: 9 lbs, 1 oz. They were both full term--I went into labor on my due date for each of them. No jaundice for either, but DD (my first) had shoulder dystocia and her clavicle broke when she was delivered. That made breastfeeding difficult because she was in pain. DS had congenital torticollis which made breastfeeding a little tricky on one side.
