My 9 week old has been on Evivo for 2 weeks now. It has definitely helped her poops. She used to have liquid-mucousy squirts with every diaper 10+ times per day, but now has 2-3 larger, yellow, seedy stools per day. My husband calls Evivo the “blowout bacteria” because she blows out usually once a day. But, I feel like she’s going a healthy amount and frequency. Also, we had been fighting a constant diaper rash since birth, but since starting Evivo that’s 98% better. However, Evivo hasn’t been the magic bullet for gas as advertised. I do think her gassiness is better, but it’s definitely still there. Our baby also has reflux (getting better—age vs Evivo??) and eczema (unchanged).
