Hello everyone! Moms who are on IV, can you tell me something? We need to switch to double feeding. We've been eating Frisco Gold, but there are no doubles anywhere since December, and the supply will be in March at best, and even then it's not guaranteed. Who has faced this situation? Can you advise what to do? Should we introduce a new mixture? Just another thing to worry about right now ? I'm afraid my baby might have a bowel movement upset if we change the formula. If we change the formula, what good alternatives are there??
