With my 1st she was on Enfamil which made her very constipated so we had to give her a little watered down apple juice everyday. With my 2nd I started using Similac that gave him a lot of gas so we tried the Similac gentleease which did not help; it even has an aweful sower smell to it. We finally tried Nestle Good Start and stuck with it. I recommend trying one formula at a time for at least a week.
