Baby’s with reflux/ dairy allergy

My daughter was born with reflux and a dairy allergy. She was strictly breastfed for 6 months and been on similac alimentum for 6 months. Her doctor did an allergy test and said she outgrew the dairy allergy. She’ll be 1 in two days so he told me try her with whole milk. We were up with her vomiting last night. I wanted to do oat or almond milk but he told me that fat in whole milk is what babies need. I don’t think the whole milk is going to sit well with her. Any other mommas doing oat or almond milk instead of whole milk?
