Any mommas have acid reflux tips? My baby girl has had reflux since she was 4 months, she's 1 now. She's had a feeding tube since birth and can't eat solids due to an overactive gag reflex. Slowing down the feedings didn't help nor does sitting up. Her therapist suggested mixing the milk with baby food and that helped for a few days and then stopped working. She's on 2 medications that aren't helping either.
