The short explanation
Expressing milk regularly helps start and keep your supply while your baby is in the NICU. Begin as soon as possible after birth, ideally within the first hours, and express as often as a baby would feed, including at night. Hand expression is useful in the first days for small amounts of colostrum; a pump can help later. Your milk is especially valuable for babies in the NICU, and even small amounts matter.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Ask the NICU team about expressing near your baby, skin-to-skin contact when possible, and how to store and label milk for the unit.
- Stress, tiredness and separation can affect supply. Support from family and staff helps.
- If supply is low despite regular expressing, talk to the NICU staff or a lactation counsellor.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell what your baby needs or how much milk you will produce. The NICU team can guide you.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- How often should I express while my baby is in the NICU?
- Can I do skin-to-skin contact with my baby?
- How should milk be stored and labelled for the unit?
- Who can help if my supply is low?
