Exclusive Pumping: How Often to Pump

The CDC says that when exclusively pumping - that is, away from the baby - you should pump as often as the baby would normally drink breast milk, to match supply to the baby's needs. ¹ It explains why: pumping as frequently as the baby normally feeds signals the body to produce roughly the amount of milk the baby needs. ¹ Below is what recognised health bodies say about exclusive pumping, quoted and linked.

How often should I pump when exclusive pumping?

The CDC says that when you are away from the baby, or exclusively pumping, you should try to pump as often as the baby is drinking breast milk. ¹ The Office on Women's Health says that if you are unable to breastfeed directly, you should pump during the times the baby would normally eat, to keep making milk. ³

How does pumping affect supply?

The Office on Women's Health says that the more the breast is drained, the more milk it produces, ² that an empty breast means better and greater milk production, ² and that when a breast is emptied it responds by making more milk. ² The Office on Women's Health adds that if the baby empties the breasts, you can then pump to remove milk and increase production between nursing sessions. ²

The CDC explains the mechanism behind exclusive pumping directly: pumping as often as the baby normally feeds signals the body to produce roughly the amount of milk the baby needs. ¹ The Office on Women's Health adds a realistic note on timing: usually, after a few months of breastfeeding, the body learns to make the right amount of milk for the baby. ²

What if I can't pump enough?

The CDC says that if pumping enough milk is difficult, adding an extra pumping session can help meet the baby's feeding needs. ¹

When should I get help?

The Office on Women's Health says to talk to your baby's doctor if you worry that the baby is not getting enough milk. ²

A note from us

We're the team behind Yael & Michal. We are not doctors, nurses, lactation consultants, or psychologists, and nothing here is professional advice.

Everything above was researched by us from public, reputable sources - we name and link every one of them below - and summarized as carefully as we could, as a free resource for other mothers. We do this because we wished something like it had existed for us.

When we name an organisation such as the CDC, the NHS, La Leche League, or the Israeli Ministry of Health, we are only citing their published guidance; it does not mean they endorse, sponsor, approve, or are affiliated with us. They have no involvement with this site, and we never use their logos or seals.

Yael & Michal sells nursing bras, which are comfort garments and not medical devices; we do not claim they prevent, treat, or cure any medical condition. The health information here is written for you as a free resource - it is separate from anything we sell.

We try hard to get it right, and we cite our sources so you can check us. But we are not a medical authority, and this cannot replace talking to a professional who knows you and your baby. Please check anything that matters with your doctor, midwife, or an IBCLC lactation consultant. This content has not been reviewed by a medical professional.
