I have never fed wellness, but have always heard good things about it. You just have to remember that because it is a "good/quality" food still doesn't mean that it will work for your baby. When I did a switch with Harley I took the list of recommended foods from the sticky, found out which ones I could get locally and then went from there. We have had to change a couple of times to find something that Harley likes and that works well with his tummy. I personally feed Merrick's Before Grain Chicken, we are on bag #2 of this and so far so good (finger's crossed).
