🥹🥹 help this mama out!

Beth

We are so in love with our girl! I had her on the 12th via c section and she weighed 5lbs 7.2oz and she lost some weight while at the hospital but gained it back and got to 5lbs 0.2oz before we were discharged but at her first appointment she weighed 4lbs 15oz… their wanting her to gain even more but I’m strictly breastfeeding/pumping and she nurses constantly I know it’s not a supply problem bc I have a good supply what are some ways I can help her gain weight? I’ve started to add one ounce of formula to her bottles hoping that would help!
