I started Evivo with my 3rd child because I read all the reviews about how it helped other babies have less gas and sleep better through the night. I even had the blessing of his pediatrician. So we tried it. At first, my baby made such a face when we started it that I wasn’t sure we could continue, but that only happened once. Now he takes it just fine. His gas definitely improved. Before he was having lots of small gassy poops several times a day. Now he usually has one big one every 1-2 days. He does seem to sleep well. Hard to say it is due to the Evivo but whatever it is I will take it. I just feel better as a Mom giving him something to help his digestion.
