My 1 month old has been on 3 ounces since she was 4 weeks old and I just went to give her her night feeding and I gave her occasional 3 ounces and she wanted more so I gave her an extra 2 ounces but she normally doesn’t finish the full too but she ate the full two ounces and is still crying for more she went from 3 ounces to randomly wanting 6 is this normal???? (She’s currently 6 weeks old)
