Dairy and soy allergy

Has anyone had any experience with their LO having both a dairy and soy allergy? My daughter has had an allergy to dairy since she was born but now at 9 months we have discovered she has an allergy to soy as well. Causes her to get massive hives and an upset stomach but the formula she is on doesn’t go above 12 months so I’m not to sure what we would do after that point. She doesn’t have very many bottles now but will most likely have a mixture of formula and solid food at a year old
