I bought this for my 9 month old after he had an ear infection and had to be put on antibiotics. I noticed that it helped his stomach stabilize and have normal bowel movements. The reason for 4 star is because of the taste. I tried it on my tongue and it is not great tasting but my little one did not mind it too much. I believe that this product does what it is suppose to do. Will buy again once I run out.
