If ur baby is vomiting, u should see ur doc. It might not even be formula reaction.

Maybe try other baby formulas. IT'S A trial and error thing until you get what baby loves. Good luck momma. You can also consider pumping. There's this storage box I saw on jumia that comes with the medela pump that stores breastmilk for 24hrs. Depending on your work, you can pump even when at work due to engorgement. Good luck mom
