Freshly ebm or frozen stash

Hi mummies, I have a stash of 7 litres of frozen bm due to LO jaundice so have to feed fm instead. Now LO can drink back bm, however we are doing mixed feeding. Also husband prefers to give freshly ebm and he doesn't want to give LO the frozen bm which are about 3 weeks long. He rather give fm. I feel heartache too..these bm are my hardwork and also painful sessions of releasing clog ducts. What should I do?
