We are struggling right now. This is the only thing our daughter knows. We have been required to try to switch however those formulas are limited too. She does not like anything flavored and I don’t blame her, they have artificial sweetener in them. We have been able to get one can of Periflex advanced unflavored and started to mix in just a bit of it daily. We are trying to use everything we can and hope we don’t run out because it is vital to her diet. It is stressful to think about because this is essential for her to drink and grow and thrive in school.
