Pumping schedule: how often and how long to pump

If your baby isn't feeding at the breast, the usual schedule is to pump every 3 hours, day and night: about 8 times in 24 hours. At work, every 3 hours is a common starting point, with about 20 minutes of pumping per session.

How often should I pump?

It depends on whether pumping replaces feeding at the breast or covers time you’re apart.

If you’re exclusively pumping

Children’s Wisconsin, a children’s hospital, gives this schedule for parents pumping for a baby who isn’t feeding at the breast:

• First days (days 1–4): pump every 3 hours, counted from the start of the last session: 8 times in 24 hours.
• From day 4: keep pumping every 3 hours, day and night.
• After 2 weeks, if you’re below your supply goal: pump every 2 hours during the day.

If you’re pumping at work or away from your baby

The US Office on Women’s Health advises pumping at the times your baby would normally eat. Breastfeeding medicine physician Dr. Kam Lam (Cleveland Clinic) suggests every 3 hours as a simple starting point, then adjusting to your output:

• If each session gives less than your baby eats, pump every 2 hours.
• If you make more than enough, every 4 hours may work.

How long should I pump for?

• Exclusive pumping: Children’s Wisconsin advises pumping until about 2 minutes after the last drops. Once your milk is in, that is often 20 to 30 minutes.
• At work: Cleveland Clinic suggests planning 30 to 40 minutes for each session: about 20 minutes of pumping, plus 10 to 20 minutes to set up and clean up.

Pumping at night

In the first days you may need an alarm to wake up at night and pump. Once your milk is in, Children’s Wisconsin advises not skipping night sessions unless you have a good supply or you need the rest.

Double pumping

The Office on Women’s Health notes that double pumping, pumping both breasts at the same time, may collect more milk in less time. That helps when you’re going back to work or school.

When to talk to a lactation consultant

If you’re worried about your supply, or a schedule isn’t working for you, a lactation consultant (IBCLC) or your doctor can help you adjust it to your situation.

Turn your schedule into reminders

Milkly reminds you to pump every 2, 2.5, 3 or 4 hours, or at your own interval, counted from your last pump or at fixed times. If a session is overdue it nudges you, and a quiet night window keeps reminders from waking you when you asked them not to.

Reminders are part of free logging in Milkly, along with sessions, the timer, today's numbers and your stash balance.
