This formula is very gentle on babies who have sensitive stomachs. Although it can cost more than other kinds and brands of formulas, for a baby who struggles with digestion, it is worth the extra money involved. Easily Digested Our oldest child had some struggles with spitting up and a gassy belly, especially when we tried using cheaper off-brand formulas. Even with the name-brand regular formulas, he would sometimes have issues (although not as badly). But when we tried this formula specifically for sensitive babies who have some of these issues, it worked very well. He stopped having issues with gas and spit-up, and he seemed a whole lot more comfortable. He also slept better at night, which I believe was a direct result of using this formula. Ease of Preparation This formula is extremely easy to mix with water in a bottle. It's not quite as convenient as the pre-made liquid formulas, but it is still pretty easy to use.
