Our son hit 3 weeks old and started having gas pains and we were told he had a little colic. We tried an over the counter pro biotic the Dr recommended for a couple weeks. Since his gas seemed mild we thought he’d be fine. But he was clearly uncomfortable and in pain. I had seen Evivo on Instagram when I was pregnant and started reading about it. We ordered it and 3 days in his belly seemed better. He was calmer and his gas definitely subsided. We have been using Evivo every day for the past 2 weeks and our son has not experienced any Colic since. This has worked for us! Thanks Evivo!!
