How much do you feed? We are currently using the wetland formula and have had great results so far! Our 13 month old girl is about 60 lbs and a little on the thin side. We have been feeding 4 cups a day, and she has put on a few lbs but recently she has not been finishing her meals. I dont want her to lose the weight she has put on. I am thinking about cutting her to 3.5 cups. How much is everyone feeding?
