Swaddle
How often you pump depends on whether you are pumping instead of breastfeeding, alongside it, or while you are at work. The basic rule is that milk supply follows demand: the more often milk is removed, the more milk is made, especially in the first weeks.
Exclusive pumping schedule by age
| Baby’s age | Sessions in 24 h | Sample times |
|---|---|---|
| 0-6 weeks | 8-10 | Every 2-3 hours, including 1-2 at night (e.g. 6, 8:30, 11, 1:30, 4, 6:30, 9 pm, 12 am, 3 am) |
| 6-12 weeks | 7-8 | Every 3 hours, one night session (e.g. 6, 9, 12, 3, 6, 9 pm, 12 am, 4 am) |
| 3-6 months | 6-7 | Every 3-4 hours, night pump often dropped once supply is steady |
| 6-12 months | 4-6 | Every 4-5 hours as solids start |
Most people pump for about 15 to 20 minutes per session, or until about 2 minutes after the last drops. Try to keep the total daily number of sessions steady when you change the timing.
Pumping at work
- Before you go back, start a small freezer stash by pumping once a day after a morning feed.
- At work, aim to pump about as often as your baby eats while you are away, often every 3 to 4 hours.
- Feed directly before you leave and as soon as you are back, if you are also breastfeeding.
- In the US, the PUMP Act gives most employees the right to reasonable break time and a private space that is not a bathroom to pump, for up to one year after birth.
Power pumping
Power pumping imitates a baby cluster feeding. A common routine, once a day for 3 to 7 days:
- Pump 20 minutes
- Rest 10 minutes
- Pump 10 minutes
- Rest 10 minutes
- Pump 10 minutes
It is popular and low-risk, but the evidence for it is mostly from experience rather than studies. If you are worried about low supply, a lactation consultant can check pump fit, flange size and technique, which often make a bigger difference.
Tips for more milk per session
- Use the right flange size. Too big or too small can reduce output and cause pain.
- Massage your breasts before and during pumping (hands-on pumping).
- Look at a photo or video of your baby, or smell their clothes.
- Stay hydrated and eat enough.
- Replace pump parts (like valves and membranes) as the maker recommends.
