How much oz for a 3 week old and how long can milk stay in fridge?

Mikela drinks 4 oz at night - sometimes 4.5 (we feed her with a bottle at night cause it just takes too long from breast). Is that too much? does that sound right?

Also, how long can the breastmilk stay in the fridge?

Thanks for your help!!!!

If she's eating it and not spitting up a lot, then she's not eating too much.

SAVE? OR DUMP?
Type of Milk Save or Dump? Why

Milk remaining in the bottle that has been offered to baby Use for next feeding, otherwise discard. Bacteria from the baby's mouth may have entered the milk during the feeding. This may lead to bacterial contamination if it sets too long (though as yet there is no research available).
Milk that has been thawed Save in the refrigerator for 24 hours after thawing, then discard. Do not refreeze. Milk that has been frozen has lost some of the immune properties that inhibit bacterial growth in fresh refrigerated milk.
Milk that has been kept in the refrigerator for eight days Transfer to storage in the freezer, or discard. Bacterial growth is not a problem, but milk sometimes picks up odors or flavors from the refrigerator or the container.
