I had a c-section, my little girl was 8 lbs 11 oz when born (wed. june 3rd). I left the hospital two days after she was born (friday afternoon) and her weight loss was normal. Although, the hospital gave us formula to make sure her sugars were normal, after the breastfeeding clinic the friday I was leaving, I decided I wanted to try breastfeeding exclusively. All day Saturday I breastfed knowing Sunday I had a check up with the breastfeeding clinic to make sure my baby was latching ok. When they weighed her, she had 11% weight lost. My question is, should I have supplemented formula with breastfeeding (making sure she was getting enough?) Do bigger babies tend to lose more than 10% body weight? How serious was it that our baby lost 11%? My husband thought she wasn t getting enough and I didn t listen. I m afraid he will never forgive me for starving our baby...it has come up in many arguments ever since.
