Formula

I have an appointment tomorrow for my daughter at WIC this will be my first appointment with her since she’s been born(2 weeks old). Well, she’s very sensitive to formula, and the only milk she can really keep down is the enfamil gentlease kind. I was wondering what kind of formula will I have to get through WIC? I know they have similac mostly, but the sensitive one she even spits that one up a lot as well. So I don’t know which formula to get, honestly. 😔
