A rule of thumb is to multiply your child's body weight times 3 to figure out the ounces your baby needs to eat in 24 hours. So, if your baby is 13 pounds, I would make sure my baby eats between 36-42 ounces a day, with 39 ounces being optimal. Some days she will eat less, somedays more. That is why I put a range in there. The formula is more important than the food at this age, as formula has more calories. May I ask what your baby weighed at birth? She is a little on the petite side for weight, but that could be totally fine is she was a little small at birth. She is on around the 8th percentile for weight, but if she were petite or you are petite it may just be normal for her.
