Does milk make acid reflux worse? Can a allergy to milk cause reflux and eczema?

Milk, maybe. To check for reflux and eczema from the milk, i suggest avoiding milk for 3 days; on the 4th day give the baby milk and see if the reflux or eczema worsens. If it does repeat the avoidance and challenge to confirm. If either condition worsens, i suggest avoiding for a month and rechecking. Most such issues resolve with a little time and patience.
