Recommended by our pediatrician for our daughter after we had multiple breastfeeding issues that resulted in that not working out for our situation. We were on a different brand of formula before our pediatrician recommended HiPP AR because daughter had noticeable reflux and wasn’t drinking enough. Our daughter has done very well on it. We saw a huge improvement in the amount drank and reflux disappeared. We did try switching to a different formula that was a little cheaper and noticed overnight a huge difference in reflux and her tummy comfort. We switched back to HiPP after a week and saw pretty much overnight relief. I'm not going to switch again.
