I haven't switched her off the formula because I was reluctant to put her straight onto cows milk after the issues we had with her brother. I thought the formula would be slightly less of an attack. We tried goats milk formula at one stage when she was 9 months (she was only having one bottle a day at a time) her poos were normal for a week and then they went back to their regualar slop. So I think she might still react to the goats milk as well
