How much breast milk does a 3-month-old need?
What this age is really about
The three-month mark is peak efficiency: babies drain in minutes what once took an hour, then get distracted by the ceiling fan mid-feed. Shorter feeds with steady weight gain mean skill, not shortage.
The pumping-mom angle
The four-month sleep regression is coming; banking a few extra ounces now is a kindness to your future 3 AM self.
Bottle math for this age
Daily ounces ÷ feeds = the bottle. At 24 to 30 oz across 6 to 7 feeds, portion storage in amounts near 4 to 5 oz so leftovers never hit the 2-hour discard rule. Small bags waste less at every age.
