I was exclusively breastfeeding our newborn and around the time he was two weeks old he started having diarrhea that wouldn't stop. He developed a rash and a yeast infection in his diaper area. My doctor's office told me diarrhea is normal at this age and it would go away. This was our fourth baby and I had never seen anything like it! I heard probiotics are a new thing to try for babies from a friend and I came across Evivo. After I got it in the mail, I started giving it to our son and his diarrhea stopped on just the 2nd day! And he just seemed to be feeling so much better. I have been recommending Evivo to all my friends who have had babies since then or are pregnant. This probiotic will only help!
