When I was one week postpartum I was put on antibiotics. I was breast feeding, and although the antibiotic was technically safe for my baby, it wiped out his gut health. He started having all kinds for gas and reflux issues and was intolerant of almost everything I ate. When he was 4 weeks old, I find Evivo and started him on it immediately. His poops have become much more regular and normal, and he is overall an extemel content baby. I was able to start reintroducing foods that were previously upsetting his tummy. I believe whole heartedly that Evivo has restored his gut health and is a huge reason our baby is so happy and content!
