My baby girl is 3 weeks old, I breastfeed her and then supplement with formula as needed, the past week I have been exclusively breastfeeding and haven’t needed to supplement with formula, and just wondering if it’s normal for her not to poop as often when exclusively breastfeeding? I was kinda worried as she had gone quite a while without a poopy diaper and gave her formula and she instantly pooped, any mamas out there experiencing the same ? Or know if it’s normal?
