I'm going to move this thread to the colic & reflux forum where others might see it easier.

My daughter had reflux and we would trial something for 1-2 weeks before adding or changing anything to see if it made a difference. So we trialled mylanta for a week & then a different medication, then we trialled changing the formula and then to a different formula until we found a combination that worked best for her. She was mainly breastfed at first but we changed that later.
