our daughter has a dairy and soy allergy, along with a whole host of others that we are discovering. The elecare saved her life. she would have had to be on a TPN tube (total parenteral nutrition) if the elecare hadn't of worked. It is very expensive, you can purchase from abbott nutrition for just under $33 a can, but if you can get your doctor to issue a prescritption and send a letter to your insurance stating that it is medically necessary, your insurance should cover it. I think we are paying like $9 a can now with insurance helping out. They also had a toddler formula that we will be moving to in a few months because the only other thing she can drink is rice milk and it doesn't have the nutritional quality she needs to maintain her weight. It was most sincerely a life saver! if this is something that sticks with your kiddo for a while, there are a few good books, Sofie Safe Cooking and The Whole Foods Allergy Cook book that have wonderful recipes that are completely allergen free. Good luck, we feel your pain!
