My 5 month old was officially diagnosed a month ago (after changing dr's). I know he's had it since birth, though. Here are his symptoms: a lot of spit up (way more than normal); crying almost all the time; hates to lay flat on back; spits up everytime he's on tummy; wants to be held a lot (to be upright); hiccups; he also spit up while sleeping (scary!!); he also sometimes chokes on his spit up, then screams out in pain; arches back while nursing; eats frequently (but small amounts). Most of that is better now that he's been on meds, but it's still not completely better.
The dr first put him on Zantac, which is an H2 blocker. Infants build a quick tolerance to this, and it helped with the amount of spit up, but not the pain. So dr put him on Prevacid Solutab (a PPI=proton pump inhibitor, these work much better!). It takes about 2 weeks to really start working, and we're on day 11. I can already tell a big difference! He's not having as many flareups.
Since he was born, I started propping up his bassinet mattress since he spit up so much in his sleep (he still sleeps in it right next to my bed). I just use a few paperback books underneath the mattress to prop it up. They do have wedges at BRU, but I'm not sure how much they are. When I put him in his crib, I'll be getting him one.
Here's a few websites to help answer more questions. The first is a blog with TONS of great info!! It helps you understand reflux, and also all the different meds that are commonly prescribed. www.refluxrebels.com
The next is a group on babycenter. It's got so many wonderful mama's who are full of info (from experience)! They can help answer any questions, or just offer support. http://community.babycenter.com/groups/a3937145/the_reflu...
If the link didn't work, under the community groups on babycenter.com, search reflux rebels and it should pop up.
It sucks having a baby with reflux, especially when you feel like there's not much you can do to ease the pain. I've cried along with my baby b/c I didn't know what else to do. My son doesn't even have it that bad compared to a lot of other babies, but I still feel so bad that he's basically been in pain since birth.
edited to add: Also, hold him upright for about 30 minutes after he eats. I know it's hard to do sometimes (especially middle of the night feedings), but it really does help!
