I don't want to tell moms what to do... or make them feel their mothering may be wrong, but I do have to say a few words when I see and read things I feel so strongly about. First of all, feeding formula can be tricky. A baby of 3 - 4 months only needs about 25 to 30 ounces a day of formula OR breast milk. Feeding formula fills them quicker and their stomach response does not tell them they are full until you see it as reflux. Also, these babies should not be on 8 oz. at one time. They should spread out over 4 - 5 oz. at a feeding. About 5 oz. every 3 to 4 hours of 5 to 6 feedings. Acid reflux comes from various things: baby isn't able to tolerate large feedings, dairy intolerance, synthetic vitamin intolerance, iron intolerance, or inmature gut. I am working with a baby with this right now and the mom stopped dairy and her vitamin... problem solved. Just wanted to pass that along.
