Pumped Milk Bottle

Ma

Anyone who is EBF currently but planning on going back to work: I have a sizable freezer stash built up for my baby for when I go back to work (in about 2.5 weeks 😢), but not sure how many ounces he should be taking per feeding/ bottle. For a 14 week old, how many ounces of breastmilk should I prep for him in bottles?
