Food Allergies Treatment

My 10.5 month old little girl had colic from 3 weeks to 5 months. Doctors determined that it was a cow milk/soy protein allergy. I cut out all dairy in my diet and she got better I was able to nurse until she was 7 months old. I tried her on nutramigen, allimentum but she was having no part of it. I tried nestle good start dha and ara and we havent had any problems for almost 4 months, not that she drinks the amount that shes supposed to, (20 ounces a day) So I thought she had grown out of her allergy. As she is getting close to a year old and is a picky eater I wanted her to stay on the formula but switch to the #2 made by good start. I tried her on 3 bottles over a weeks time of half old/half new and profuse vomiting within 5 mins of taking bottle. So what do I do when she turns one. Do I try her on the Whole milk, Do I have any other options?? or keep her on the baby formula thats been working so far??
