My LO was slow to get back to his birth weight. He was 7 lbs 5 oz at birth and 6 lbs 10 oz at 2 weeks and 6 14 at 4 weeks. Our ped. told me I wasn't making enough milk and needed to limit breastfeeding to 10 mins per side and then supplement by offering a 2 oz bottle after every feeding. She even gave us 2 boxes of pre-made bottles after i told her we had a can of powder formula at home (for emergencies) LO was having plenty of wet diapers and BMs so I was really confused. I knew that pulling him away from the breast without finishing was a bad idea so instead I started offering one 2 oz bottle in the evening when he was extra hungry and didn't seem to be satisfied. I did this for one week and he gained 10 oz! The next week he gained 6 oz! Our ped was not impressed and advised that I needed to start giving him 4-5 oz of formula per day. I was so angry. DH doesn't know much about breastfeeding and weight gain and tells me he is "worried" about our son because I am not giving the extra formula. I am now in the process of switching to a pro-BF doctor. The in laws have even made things worse. They called DH and told him when he was a month old he weighed 11 lbs and he was born 7 lbs. I have heard comments such as, "maybe there isn't enough nutrients in your milk", "is this (slow weight gain) going to affect his development?", MIL even said "he looks anorexic" I cried after that one. FIL recently told me i should wean LO before going back to work he even suggested a good formula. How do I respond nicely to these comments? These people formula fed all their kids and didn't have any weight gain problems so it's as if they think formula is best. LO is 8 weeks old now and weighs 8 lbs 10 oz. He's gaining about 6 oz a week. Would he gain faster if I switched to formula? I used to like the in laws but now I can't stand them. What do I do?
