My daughter was delivered via C-Section and I was on antibiotics during the delivery. Taking those two details into account, along with the fact that I am an older mommy, had me worried about her gut health. My family has a few health issues directly related to gut health, so I knew early on that my daughter would be on probiotics as soon as possible. I noticed a change in her about 3 days after taking Evivo. She slept a bit longer, fell asleep easier and her tummy issues decreased. As a nursing mommy I was able to add dairy back into my diet without seeing it affect her as it did prior to Evivo. Gut health is key to lifelong health and I am very happy I found Evivo.
