how often do you pump breast milk

Most breastfeeding experts suggest pumping often enough to mimic how frequently a newborn would nurse, then spacing out sessions as your baby and supply stabilize.

Core guideline: how often to pump

  • In the first weeks (building supply), aim for about 8–12 pumping sessions in 24 hours , roughly every 2–3 hours, including at least one overnight session.
  • If you are exclusively pumping , a common target is 8–10 sessions per 24 hours until your supply is well established.
  • If you are pumping while also breastfeeding , many parents add 1–2 extra pumping sessions per day (for example, after the morning feed) to build a small freezer stash.
  • Once your supply is stable and baby is older, many people gradually reduce to about 5–6 sessions per day , as long as baby is gaining well and your breasts aren’t staying uncomfortably full.

How long each session should be

  • Typical sessions last 15–20 minutes per breast or until your breasts feel soft and milk flow has mostly slowed.
  • A helpful rule of thumb is to pump about 2 minutes after the last drops or sprays, rather than focusing only on the clock.
  • When trying to boost supply, some parents pump 10–15 minutes longer after breastfeeding to signal the body to make more milk.

Situations and sample rhythms

These are general examples, not medical advice—your own plan should come from your healthcare provider or lactation consultant.

  • Exclusively pumping a newborn (first 2–4 weeks) :
    • Start as early as you can after birth, ideally within 6 hours if baby isn’t latching.
    • Aim for 8–10 (sometimes up to 12) sessions per 24 hours , not letting more than about 4–5 hours pass at night in the very early days.
  • Back at work, baby also breastfeeds at home :
    • Pump at work about every 3–4 hours for ~15 minutes , ideally on the same schedule as your baby’s feeds at home.
  • Supply below goal :
    • Many hospital and children’s-center guides suggest increasing to every 2 hours during the day while keeping night sessions around every 3 hours, aiming for at least 8 sessions per day.
  • Supply at goal and stable :
    • Maintain about every 3 hours (around 8 sessions daily) or whatever rhythm keeps your breasts comfortable and baby satisfied.

Mini “Quick Scoop” recap

  • Newborn phase: about every 2–3 hours , 8–12 times per day.
  • Exclusively pumping: 8–10 sessions in 24 hours to reach and maintain full supply.
  • Mixed feeding (breast + pump): add 1–2 daily pump sessions , or pump to match any feeds you miss (for example at work).
  • Typical duration: 15–20 minutes per session , or until your breasts feel soft and milk flow slows.

Because every body and baby is different, the “right” schedule is ultimately the one that protects your milk supply, keeps your breasts comfortable, and fits your daily life—ideally planned with a lactation consultant or healthcare provider who knows your situation.
