I know it is a little more expensive, but you could try the formula that is ready made (only in the glass containers though, since there is a chance the ones in the steel cans actually have a bad chemical in them for babies). Anyhow, if you use the ready to use liquid formula, she might take it. My baby wouldn't take the powdered formula, but instantly took the ready-made formula when we mixed it with breast milk. Will the baby take a bottle with just breast milk? We also had to by "breast flow" bottles because they are more like the actual breast and the baby has to suck about the same as they would to get it out. You might want to try those suggestions. Good luck!
