Power pumping: schedule and timer
Power pumping means pumping in short, repeated bursts for about an hour, to imitate a baby's cluster feeding. The most widely published schedule is pump 20 minutes, rest 10, pump 10, rest 10, pump 10.

What is power pumping?
Power pumping is a way of pumping in a burst of short sessions close together, usually for about an hour, instead of one longer session. The idea is to imitate cluster feeding, when a baby feeds very often over a short stretch of time.
No health agency publishes an official power pumping schedule. The patterns below are the ones written into research protocols, and they are the most widely published.
Power pumping schedules
| Schedule | Steps | Total |
|---|---|---|
| Classic hour | Pump 20 · rest 10 · pump 10 · rest 10 · pump 10 | 60 minutes |
| Even hour | Pump 10 · rest 10, repeated through the hour | 60 minutes |
Both patterns appear in the power pumping arm of a registered US trial protocol (NCT03851718). That trial was later withdrawn before it reported results.
How often to power pump
The same protocol asked mothers to power pump for at least one hour on at least three days within a five-weekday period, preferably three days in a row. In a pilot trial from India, mothers power pumped once a day for seven days.
The term is not used the same way everywhere. Lactation consultant Kelly Bonyata (KellyMom) uses “power pump” for something broader: two or three days of resting, nursing very often and pumping after as many nursings as possible.
Does power pumping work?
The evidence is limited. In a small pilot randomized trial of mothers of very low birth weight babies with low milk output, power pumping once a day for seven days gave more milk per session than routine pumping: a median of 50 mL against 27 mL on day seven. The share of babies exclusively breastfed at hospital discharge was not significantly different between the two groups (61.1% against 50%).
That is one small study in a specific group. It does not show what power pumping will do for you, and no schedule guarantees more milk.
When to talk to a lactation consultant
If you are worried about your supply, talk to a lactation consultant (IBCLC) or your doctor. They can look at your whole situation, and power pumping is only one of the things they may suggest.
Power pumping in Milkly
Milkly runs a power pumping block with preset intervals, 20 · 10 · 10 · 10 · 10, or your own scheme. Follow the session on the Lock Screen and in the Dynamic Island, and pause or finish without unlocking.
Each session is saved with a Power pumping tag. Full history and trends are part of Pro, and your first week is on Pro.
