What should you know about milk supply getting low?

Breasts may feel softer without producing less milk, especially after the early weeks when fullness often settles. A baby may also feed more frequently during a growth phase. More useful clues include swallowing during feeds, contentment after some feeds, regular wet nappies, and steady growth assessed by a clinician. Pumped volume alone does not always reflect what a baby can remove at the breast.

Supply can dip when feeds are routinely shortened, bottles replace breastfeeds without pumping, latch is uncomfortable, or a breast pump does not fit well. Stress, exhaustion, illness, and some medicines can also affect feeding or milk removal.

Offer the breast when the baby shows early hunger cues and allow time for active swallowing. Check positioning and latch, and offer the second breast when the first side has slowed. If a feed is replaced, expressing around that time can help maintain the pattern of milk removal. Keep a short record of feeds, wet nappies, and concerns rather than judging supply by breast fullness.

A lactation consultant can observe a feed, check milk transfer, and help adjust pumping or feeding technique. See the Lactation Consultation service for focused support.

Arrange prompt medical advice if the baby is unusually sleepy, has clearly fewer wet nappies, cannot stay latched, or is not feeding effectively. Seek urgent care for breathing difficulty, marked weakness, or signs of dehydration. Contact a clinician if you have fever, a hot painful breast area, or worsening redness, because these symptoms need assessment.

Ask: How can we tell whether milk transfer is adequate? Could my medicines or health condition affect supply? Would a weighted feed, latch review, or temporary expressing plan help? What signs should prompt same-day assessment?
