We starting using Parent's Choice Sensitivity Formula after we were told that our son had a sensitivity to lactose, as a lot of babies do. So our pedi suggested we try Similac Sensitive, and after comparing the nutrition facts of the two formulas, we noticed that the Parent's Choice Sensitivity was exactly the same and 1/4 of the cost!!!! How can you go wrong? The quality has been great! Very consistent in every can. Mixes well with water, doesn't leave big globs of powder, and doesn't get foamy when shaken. My son has had SOOOO much less gas pain because of the switch, and we are very happy...
