We are not coping. My children have used Phenex since they were newborns. It’s all they know. Metabolic formulas can be very off putting in taste unless having been on it for a while. So trying to find a new product has been extremely difficult. We have tried every options there is but again a lot of formulas from other company’s are out of stock because of this. We have yet to find a replacement and I’m extremely worried for their health. Are biggest struggle is getting them to even tolerate the smallest amount of a new formula, and finding ones that we can get our hands on.
