My son was diagnosed by accident. We had problems feeding him from the start. Being in incredible pain during and after each feed. It was nothing short than a nightmare. People kept saying, babies cry, everyone goes through this, its normal. But in my heart I knew it was not. Anyway we were at the Peadi to check JD's enlarged kidneys and it was feed time. JD did the usual thrashing around and screaming. After a few minutes the Dr said, nope this is not normal he has reflux. We put him on Zantac and AR formula. And although he still had the reflux at least the Zantac reduced the acid in his tummy so it didn't burn him on the way up. With permission from the Peadi we started him on solids at 3.5 months and he has been thriving ever since. Now he is off the Zantac, but the transition to Step 2 formula is proving to be difficult as he is used to the very thick AR formula. Will see how we go.
