Regarding blood/muscus in stool. I have tried to switch my baby to Innova but it did not work no matter how slow I've tried to do it. He was on rice/chicken diet and got better but the minute he eats Innova even a bit he starts to get loose stool with bloody muscus in it. I thought it's an allergy to chicken but it's not. He eats other foods with chicken fine. Then I thought it's barley, eggs etc. I still cannot pinpoint it. I tried all of them separately and he was fine. I got lost in exclusion process
I just don't feed him Innova anymore. If switching slowly (let say in about 7-8 days) does not work then don't keep him on Innova. My baby had pretty bad problem with it and was not feeling good at all. I did not suspect food in the beginning because it is a very premium food.
