not sure tbh. I was breast feeding, but she was taking over an hour to settle after night feeds, and making very loud breathing sounds. we tried soy formula because DS is mpi and we assumed that was the problem. within 5 days she was so constipated that the doc prescribed the nutramigen. she has been on that ever since, was weaned on dairy free food, but has been tolerating cooked and hidden dairy for a couple of months
after we saw tthe paed last time he suggested we trial her, that's when I started the milk in cereal and yogurts. that's been about 3 weeks now.
