My 7 week old was diagnosed with silent reflux when she was 3 weeks and was prescribed zantac for it. Fast forward to now, 4 weeks later, and she is doing muuuch better with her silent reflux, However just a couple days ago she started projectile vomiting pretty often. It's not after every feeding but its been at least 2-3 times a day now up to 5-6 times a day. Im not sure whether this is still a reflux issue cause she's on zantac so i feel like that should take care of it, unless her dosage needs to be upped. But then i started wondering if it might be an allergy to something im eating. I already cut out dairy when she started having the silent reflux issues a month ago, but im vegetarian so i didnt cut out soy. She also has had a small rash under her chin and around her neck that just started showing up. I just cant see how it could be an allergy cause im not eating anything different from a month ago. Has anyone experienced this kind of thing? Im calling the pediatrician tomorrow but im curious now
