How much breast milk does a newborn (first week) need?
What this age is really about
A newborn stomach starts cherry-sized: about a teaspoon on day one, an egg by day 10. Feeds are tiny and constant by design, and colostrum's small volumes are exactly right. Watching a full bottle disappear is not the goal this week; wet diapers and weight checks are.
The pumping-mom angle
If pumping from birth (NICU, latch troubles), collect every drop in syringes or small bottles and feed the freshest first. Volumes of 5 to 30 ml per session are genuinely normal in the first days.
Bottle math for this age
Daily ounces ÷ feeds = the bottle. At 10 to 20 oz by day 7 across 8 to 12 feeds, portion storage in amounts near 0.5 to 2 oz so leftovers never hit the 2-hour discard rule. Small bags waste less at every age.
