This has been a life saver! My son who is 7 weeks old has been my fussiest baby by far. He was diagnosed with reflux, and just always seemed to be in pain. He would have close to 10 poopy diapers a day.. but it was watery, acidic and not a lot at a time. His bum was always so red despite changing him and applying butt cream constantly. He never wanted to be put down and would scream when he was. I stumbled upon Evivo and decided to try it out of desperation. I’m SO glad I did. Within a day I noticed a difference. He’s a new baby! He’s a happy little guy, who can handle bring put down for a few minutes now 😊 He is now pooping more normally- less frequent and it isn’t scalding his skin. He doesn’t cry non stop- and overall is much happier!! I’m sooo beyond thrilled!! It’s also worth mentioning I am breastfeeding but also supplementing with formula as well. I know this product wasn’t studied with formula fed babies.. but my baby does get formula and it still has worked wonders!! Buy it! You won’t regret it!
