Just got home from my sons 4mo check up and he was two oz less then he was at 2months!! He is two inches longer but I'm freaked out. At birth he was 8lb9oz... 2 mo he was 12lbs8oz and now 12lbs6oz. He is EBF and I pump at work. He eats 2.5 oz every two hours when I'm gone and seems completely satisfied and when I'm home, he nurses constantly and until he's content. He has adequate output in diapers. Dr wasn't worried...said he only would be worried if at 6 mo he was the same. Should I add more to his feelings when I'm gone? My other son was always at 2oz every two hours and at like 5 mo went to 3. Eeekkkkk I'm freaking out.
