We give her simethicone in every bottle. It helps some and at least prevents some gas from making it into her intestines. We switched formula as I wondered if she had the same lactose sensitivity (not lactose intolerance) I have but it didn't make a difference. It's definitely intestinal gas, not stomach, that gives her so many issues. We started doing tummy massage 30-45 min after every bottle during the day as of last night.
