I'm asking for a friend. Baby can't breast feed and reacts to cow milk. Pediatrician said she would (presumably automatically) react to other dairy like goat milk (and I read that goat milk isn't really a good substitute for human breast milk anyway). So the pediatrician put her on a formula that has high fructose corn syrup as the first ingredient

Has anyone faced this issue? I'm not sure I trust random online DIY recipes and testimonials for formula to really provide something I could feel confident enough to suggest trying. I would think human breast milk is quite specific and not easily replicated.
Any guidance or experience here would be greatly appreciated.
