N.C.
My 3.5 month old has had reflux since he was 2 weeks old. He's been able to take Prevacid, however, it took me going to see a Pediatric Gastroenterologist in order to get some more detailed information/knowledge about reflux. I felt tons better after the visit.
Something I tried was Colic Calm. It was an herbal remedy much like Gripe Water that seemed to distract him from the irritability. you can get it at www.coliccalm.com. I've since have had to stop using it - but at the time I couldn't live without it.
If you need the name of the GI I'd be happy to give you their info. They were amazing.
Good luck!
