Anyone try goats milk?

Hi yall! My boy is 4 months old with a CMPA. We’ve been on nutramigen since he was 3 weeks old. It has helped his symptoms SOOOO much. At 4 months he’s hardly spitting up anymore. His reflux has been controlled (for the most part) with famotidine and he’s a generally happy baby. I just feel so bad that it’s so processed and the formula is SO expensive 😩 has anyone had any luck with goats milk formula and CMPA? We’ll absolutely ask pediatrician at his appt next week, just curious.
