My 7 month baby has acid reflux; what can help his pain without giving medication?

Alter feeds. Some reflux kids will improve with smaller, more frequent feedings & elevation of the head for at least a half hour after feeds. Thickening the feeds (cereal) also sometimes helps. Decades ago we suspended some of the worst on a wedge of foam in a parachute like harness that kept their head up. If all else fails u may get tired of baby crying about the heartburn & try the med.
