My son is now three weeks old over a week ago he was diagnosed with AR. The pediatrician put him on Zantac. Originally he was taking it every 12 hours but after two days of no change the dr upped his dose to every 8 hours. At his recheck this week (1 week after beginning meds) there was still no change so they put him on prevacid once every 24 hrs. today is his second day and he still has no change.... I know some medications take time but he just gets sooo fussy and in pain that I don't know what else to do. I have also been giving him some gripe water which seems to help a little. i just want him to feel better and for my husband and I and the baby to get some sleep. He has not been sleeping longer than 1.5 to 2 hours at a time due to all of the pain/fussiness. I would really appreciate some advice!
