T.B.
I'm so sorry to hear that you are having to deal with this. I'm sure that it breaks your heart and brings you endless frustration as it did with me. My son had reflux too. I think that it was around 4 weeks he had an upper GI done to diagnose it. We ended up putting him on Zantac. He had to take it as much as 4 times a day until he was almost a year old. The dr. gave us previcid first because you don't have to give it as often, but it didn't work for our son. The Zantac made a HUGE difference. He still did spit up and I really had to watch what I ate (nursing). Foods that generally cause more acid for you pretty much do the same for your baby. I tried gripe water after many people recommended it, but it made no noticable changes with my son after using it regularly. My doctor also ended up recommending that I start him on rice cereal a little early. We started at 3 1/2 months. I've heard of people starting as early as 3 to help. It also did help us.
I hope that this helps in some way. My son is 2 1/2 today and has no problems at all with it today. The first year was horrible and I hope that you have a good support system to help you if it does turn out to be bad reflux. If nothing else email me and I'll help you get through it!
Blessings,
T.
