Formula at 4 months

so i’m 19 weeks pp now and yejin is 4 months old. we started supplementing with formula at 6 weeks and it’s been a game changer. but i’m wondering, does anyone else have trouble finding a formula that their lo likes?

we’ve tried a few different kinds and yejin seems to spit up a lot with some of them. i’ve been tracking her feedings and spit ups in careclinic, and it’s helpful to see the patterns, but i’m still stuck on what to do. anyone have any advice on how to find the right formula?

or is this just a trial and error thing?
