Normal???

Chelsea • Zakiahs Mommy 💕

We breastfed until 5 months but we supplemented with formula since 2 months. At 5 months she was no longer interested in the breast she wanted the bottle more because she was actually getting full. She’s 6 months now and still only takes 4 oz every feeding. Some times she don’t even finish the whole thing. Is this normal???? Shouldn’t she be drinking more by now?
