My guess is if your doc prescribed the medicine, your lo likely needs it. I would do the wedge in addition to the Axid. (Along with keeping upright at least 30 minutes after feeding). Do everything you’ve read about for the reflux to help your little one, and hopefully it will all help!! I’m not sure, I havne’t done a ton of research on it, but I don’t think there is a ton of research on the meds in children anyway since most people would not submit their own children to medical trials. You can visit http://www.marci-kids.com, though, and they have done studies and have great info about childrens reflux. Hopefully the Axid helps your little one, most kids on this board have had to “move on” to PPIs (Prevacid, Prilosec,Zegerid), because the H2Blockers just don’t work well enough for them.
Best of luck, and know that there are a lot of knowledgable people here who can help you with any questions.
