I have a 4 month old and a 4 yr old. Both were born with silent gerd, which was acid reflux , but not projectional ..it rose and fell in the chest. My little guy squirms when I give him the bottle , and looks very uncomfortable when feeding. What has always worked with both of my children was 1 teaspoon of rice in the bottle to keep the acid down and from rising. Meds were told by their pedi for severe cases, you should look to all options before giving meds....i would make that my last resort. Also, kept my children elevated at all times . Laying flat kept the acid rising. While being elevated the acid stays down. I wish you luck.
