My little boys had an extremely hard time switching from breast-feeding to formula when he was 6 months old. Not only did he just want mommy, but we tried like 10 different formulas, and they all gave gave him gas pains and digestion issues, so our pediatrician recommended lactofree lipil. Low and behold, it solved all our problems almost immediately, and we had a happy healthy baby. I'd like to note that he is now older, and does not have a lactose intolerance to any degree, but there was just something in this formula that helped him not have any of the issues that the others were causing him--and we were so thankful to have found something that worked. When he was a baby, the product was really hard to find in stores--I don't know if it was being carried in many stores, or the demand was so high that they were always out. Regardless, I always made sure to keep an eye out, and when I did find any I stocked up, so that I would always have a happy baby!
