I think you can store milk in the refrigerator for up to 5 days (depending on temperature so I guess you can pass the freshest bm on monday to consume til wednesday and if possible to feed freshly expressed milk on days you are on ML, that would be better.
You can keep bm chilled up to 5 days, so Thursday's milk can be used till Monday and Friday's bm can be used till Tuesday and so on. For Thursday and Friday you can use Sunday's and Monday's bm. Hope this explains.
