Considering the actual effectiveness of the product, this product is very good at helping babies who have suffered from diarrhea. When our children have started to struggle with this problem, we were looking for a formula that would help reduce the problem, help them be more comfortable, and help them sleep better at night without an upset stomach. This formula has worked quite well for us, and we have been pleased with the results. Easily Digested Our children have never had digestion problems with this product. Even when other formulas gave them diarrhea and upset stomachs, this one always seemed more gentle for them. It is easy for their bodies to digest and process without ongoing issues with diarrhea. As a result, our children have returned to sleeping through the night much more often with the use of this product. Ease of Preparation This formula is very convenient to use, since it simply requires opening the container and pouring into a bottle (making sure that it is the right temperature, of course). Preparing a bottle simply cannot get much easier than this, and the ease of preparation is this formulas best quality. The one downside to it that I have noticed is that the whole bottle needs to be used relatively quickly once it is opened, much sooner than the other powdered formulas that we have used. It is not something to buy a whole bottle and only use once in a great while.
