My little boy will be 5 weeks on Thursday and he's still not gained back his birth weight. He's still 4 oz under. He's always peed and pooped plenty, so I've tried to just be patient and not worry. Well, we saw the doctor yesterday and he gave us formula and told me to feed him 2 oz after every feeding, but the thing is these past few days he's been eating a LOT and I think now my milk supply is right where it needs to be. I finally feel like he's getting what he needs and I'm so worried about messing it up with the formula. We have an appointment tomorrow to check his weight again and I see a lactation counselor on the 2nd of December. Should I just supplement like the doctor wants until I get to see the lactation counselor? Would pumping while he takes a bottle help keep my supply up? And how long/how much should I pump?
