Hello, I don't often post on the forum but this topic is one I?ve had a lot of experience (lack of sleep/tears!) with. I have 2 children both who have had protein intolerance, now 3 & 5. My first finally went onto neocate at 12 weeks, after 5 weeks of no feeding and various hospital/doctors appointments. We finally saw a paediatric gastroenterologist at GOSH privately who diagnosed it, and 3 weeks to the day of swapping formulas - as per his info - she was a changed (normal!) baby. We saw the signs in our second a lot earlier, and he too went onto Neocate. Both of our children were weaned at normal times, but we were quite slow in introducing foods in case of other allergies. Both now are great kids - with a very wide diet and no allergies. From my experience and from a lot of advice from our specialist we now feel ?reflux? in this instance is very much more of a stress for the parents than for the kids. I?d be more than happy to get more in depth if you want to PM me. It was a very long and very stressful period for us! Good luck J edited to say my first had reflux until well after she was 1 but was gaining weight and happy - I just had to take a cloth with me everywhere I went!
