Reflux issues

So I know some ppl may disagree even talk crap but I wanted to see what you ladies thought. My son has reflux to the point he has episodes and I can hear it come up his throat. We have tried famotidine and it made it worse. I won’t try enfamil AR because formulas have a bunch a crap in them. My son is on Kendamil Organic which is from Europe and is all clean ingredients. I’ve heard some moms say adding a tiny bit of oatmeal will help with reflux. I’m thinking once a day or twice adding 1/4 tsp to 4 oz of milk. What are your thoughts on this? My son is 3 months.
