Breastmilk changes as kids get older. Giving a baby frozen milk here and there or to supplement is obviously totally fine. But I wouldn't want the majority of my child's milk in a day to be frozen from a previous period. I sent my kids with fresh milk every day, and even saved Friday's milk for Monday every week with no issue.

@shabang: this is exactly what I did.

I usually would provide fresh milk Tues-Fri, freeze Friday's milk, and provide older frozen on Monday. Fresh milk has the highest amount of antibodies/helpful living cells so I like to maximize it while also ensuring freezer stock is rotated. Also it's easier and uses less freezer bags to not freeze every day.

It sort of depends on what's going on with my LO, but generally I freeze Friday's milk but re-thaw about 2/3 of it on Monday and combine with some older milk. Then Tues-Fri, he gets fresh milk mixed with a small amount of frozen milk as well (maybe 1-3 oz frozen). If he's sick though, I try to just give him all the most recent milk so he can get as many antibodies as I can give him.

I WFH a few days a week, and go in to the office the rest of the time. I nurse on my WFH days, leave fresh pumped milk whenever I have it available, and pull from the freezer the rest of the time. I usually end up freezing my whole output on Friday and often on Tuesday too, just because that's how my schedule works.
I've posted a little about my supply dropping lately, so, at this point, even when I leave fresh milk, my nanny will sometimes have to unfreeze a bag to tide LO over at the end of the day. I'm cycling through my freezer supply pretty quickly because of that.

@Truth Bombs: this!
@snowjewelz: I send fresh milk from the day before, like you said. For Monday's milk it's a combo of weekend pumped milk and usually a frozen from the stash. I have a tiny stash at any given time (maybe 25 oz?) and try to not let anything sit in the freezer longer than a month or so.

Fresh T-F, frozen M and now that I only pump 1x a day I make up the difference with frozen too.

I try to use one frozen bag per day and typically split it between two bottles and then top off with fresh milk from the day before. Without using some frozen milk everyday, I don't think I would cycle through my stash fast enough.
