I lived through a colic baby too! What I did learn was to keep the child on a schedule, at least 3 hours before feeding again. The new formula set on the old partialy digested formula and fermented. Hence the distress, for baby and parents! Between feedings give the baby water and plenty of it. This will satisfy any hunger and keep the stomach from becoming upset. That was the best advice I got, and passed it onto a set of new parents who were doing the same, feeding too frequently.
