my lo is on comfort milk as she is very unsettled And screams a lot. this hasn't seemed to help and after feeds she seems to get griping pains that cause her to tense and be in a lot of pain, it's heart breaking. the Dr has put her on gaviscon but I'm unsure if this is working. I am tempted to try lactose free milk and gripe water, I was lactose intolerant as a baby and have a lot of allergies. has anyone changed to lactose free formula or have any experiences?
