Low milk supply after delivery: what to know

In the first days, breasts produce small amounts of colostrum before mature milk increases. A baby may also transfer less milk when the latch is shallow, feeds are unusually short, or sleepiness makes it hard to stay attached. Breast fullness is not a reliable measure on its own, and a pump may remove less milk than a baby who feeds effectively.

Useful signs include swallowing during feeds, relaxed hands after feeding, regular wet nappies, and weight checks with the baby's clinician. Pain, breast surgery, heavy bleeding after birth, thyroid problems, retained placental tissue, and some medicines can also affect production.

Offer the breast often and respond to early feeding cues such as stirring, hand-to-mouth movements, or rooting. Keep the baby close, use skin-to-skin contact, and check that the mouth takes in a deep mouthful of breast rather than only the nipple. If a feed is missed or milk transfer is poor, expressing around that feed may help protect stimulation.

Arrange a feeding assessment with a lactation professional. They can observe positioning, assess milk transfer, and help choose between hand expression, pumping, or temporary supplementation while protecting breastfeeding goals.

Contact your baby's clinician promptly if the baby is difficult to wake for feeds, has noticeably fewer wet nappies, appears increasingly weak, or is not meeting weight-check expectations. Seek urgent medical help for a baby who is very hard to rouse or has breathing difficulty. Contact your own clinician for fever, a hot painful breast, worsening redness, heavy bleeding, or dizziness after delivery.

Ask: Is milk transfer adequate at the breast? Should the baby's weight or nappies be checked sooner? Could my delivery, medicines, or a health condition be affecting production? What expressing plan fits our feeding goals?
