Milk options

Anyone looking into pea protein milk? My son is on nutramigen right now due to allergies and doctor said we’ll try cows milk after he turns 1 or lactaid if he doesn’t do well with cows milk... but i was thinking of going plant based with milk and the best option I’m seeing so far is pea protein milk or soy milk. The brand I was looking at is Ripple (pea protein). There’s so many mixed reviews on soy that I’m not sure about it( I mean I drank it when I was younger bc Of my milk allergy and nothings wrong with me but idk.) Just wanted to see if anyone else is doing research on anything similar or if anyone has any experience with plant based milk with their older kids and have any advice ! Thanks in advance :)
