It's been about two weeks that my almost 3 month old baby starting using Evivo and wow, what a difference. Since birth, my baby had trouble with reflux and colic. Starting around 6pm, he would cry inconsolably. Throughout the day he also struggled with spitting up, vomiting, and pooping too often (even when he passed gas). My doctor suggested a different probiotic that didn't help much. My lactation consultant recommended Evivo instead and I wish we would have started here! Evivo helped develop his gut health. Within two days of using it, my husband and I saw improvements. Now that we are more than halfway through our month's supply, he's doing so well!
