Desperate

My babygirl is 12 weeks and is having a terrible time with gas, shes went from breast, pro advance, advance, sensitive, soy to aliementium. Shes been on the aliementium for about 3 weeks now and it's just tearing her up and I feel so bad I dont know what else to try. We didn't have a problem when we were using the RTF pro advance in the hospital or when we got home, but wic wouldn't cover it they said it's the same as advance but when she went to advance it just made her have a hell of a time. I'm 100% willing to drop wic and buy whatever I need to buy for my babygirl to feel better(even if I go into debt) She went from sleeping all night, everynight to crying in pain. She went from eating 6oz every 6 hours to eating 4 every 2 hours.

So what would you do?

Stick with it and see if it goes away or revert back to what she was doing good on? I HATE to jump around with her formula but I'm desperate to have my peachy back to her normal happy self

I've tried gas drops and gripe water. I've tried adding half a baby spoon of rice cereal to her bottle (she has reflux and pedi approved it)

I'm a ftm so I really just dont know, I live with my mom and she doesnt know either. Her dad had the same problem but his parents have passed so we cant ask.

And no, I cant breastfeed. I've tried to bring my milk back. With cookies, vitamins, mother's milk stuff, power pumping. Nothings worked :(

Has anyone ever had problems with powder formula but not RTF formula? I've read there's a couple corn something or another ingredients that can hurt babies bellies in the powder and not in the RTF which I have checked and the ingredients are different but I'm really just asking.

Please help me help my baby, No baby deserves the pain shes in :'(
