I started trying out Evivo at my daughter's 2 month birthday after a month of inconsolable crying, hoping it would improve whatever we couldn't figure out was giving her a hard time. It's been 13 days now and she not only hasn't spit up since we started feeding her the probiotics (normally she would projective vomit all over us every other day or so!), but she just seems like a calmer, happier baby in the evenings. Thank you, Evivo!
