I am a pediatrician with 2 month old twin boys with colic—they have been crying most of the day since they were about 2 weeks old. After I tried an elimination diet (no diary or soy) and probiotics without much improvement, I became desperate so ordered Evivo after seeing all the ads. After 2 weeks of basically force feeding them the grainy concoction, with them spitting a good amount of it in my face every time, there was no improvement in their fussiness. The only change I noticed was more foul-smelling, explosive bowel movements. They are still gassy and their eczema is actually worse, not better. The research behind Evivo sounded so promising, and maybe my boys are just fussy babies no matter what, but I really saw no improvement whatsoever. Obviously I cannot speak to the long term effects of Evivo but so far I am disappointed.
