J., my son was diagnosed with acid reflux at 7 weeks and put on Zantac, which worked wonders for him. After his first birthday, his pedi suggested we wean him off to see how he would do, and all went fine with that. He's been off meds for more than a month with no issues, but he recently started eating more and different kinds of table foods, and it seems to have returned (very wet burps, bad breath, throwing up, waking from naps and nighttime sleep with fits of uncontrollable screaming). Per his pedi's instructions, we started him back on Zantac two days ago, and we've had no incidences of vomitting or waking since. She said this would be temporary until his body "caught up" to his new feeding habits. I'm not thrilled about him being on medication, but after seeing the improvement over the last 48 hours, I'm happy to return to it as long as it's needed. Best of luck!
