Daily totals vs per-session: why dailies win
Exclusive pumping daily output is what matters for feeding your baby, not whether one session yielded three ounces or one. Morning pumps are often highest; before-bed pumps may be half.
Track seven-day averages of daily totals. Stash rolls up session volumes on iOS so trends are visible without end-of-day math.
Expected oz per day by age (exclusive pumping)
Ranges vary widely. Use these as benchmarks, not pass/fail grades.
- Weeks 1–4: building phase; often 15–30 oz/day by end of month one
- Months 1–2: often 24–40 oz/day as supply establishes
- Months 2–3: often 22–38 oz/day; regulation may briefly dip totals
- Months 3–6: often 24–35 oz/day for many established pumpers
- Months 6–9: often 20–32 oz/day as solids begin
- Months 9–12: often 18–28 oz/day
- Per session (established): often 2–4 oz combined; morning highest

When 1 ounce per session is normal
Normal: Colostrum weeks; one end-of-day session; one side when the other carried the session.
Investigate: Every session low for days with falling weekly average and baby not meeting intake.
Run the EP output check tool to compare your daily total to age benchmarks.
Match output to your baby's intake
Use our baby milk need calculator for intake estimates.
If daily pump totals meet or exceed what baby drinks plus a small stash buffer, you are on track.
Check your output against benchmarks
The free exclusive pumping output check compares your oz per day to typical EP ranges by age.
