Anyone on wic!! For formula??

My LO needs his formula switched the dr just told us to look into what we want and I mentioned he’s on wic and she said oh wic will send me a form to fill then they will switch it but I’ve heard other stories and people say they need a prescription they take to the wic to be able to get it switched, and our dr said wic sends her a form idk what to do

Does wic even switch formula ?

My lo has trouble with spit up he’s throws up a lot of his formula the dr gave him meds for acid reflux but he still throws up a lot so I’m hoping switching up formula will help
