Breast Milk Expression and Storage

Why Might You Need to Express Breast Milk?

Not every mother can breastfeed directly at every feed. Returning to work, temporary separation, milk overproduction, a baby in the NICU, or even baby’s refusal to latch can all be reasons to express milk. Expressing milk helps:

  • Protect the mother’s health (preventing engorgement or mastitis)
  • Maintain milk supply
  • Ensure the baby continues to receive breast milk even when apart

It’s not an alternative to breastfeeding—it’s a way to support and extend it.

Methods of Expressing Breast Milk

Hand Expression

The most natural and cost-free method.

Advantages:

  • No equipment required
  • Gentle on the nipples
  • Allows better control of milk flow

How to do it:

  • Use a warm compress to soften the breast
  • Place thumb and forefinger in a “C” shape just outside the areola
  • Apply light, rhythmic pressure and release to stimulate milk flow

Manual Pump

Hand-operated devices ideal for occasional use.

Pros:

  • Quiet, portable, and doesn’t require electricity

Cons:

  • Requires physical effort
  • Not ideal for double pumping or regular use

Electric Pump

Available in single and double models for more efficient expression.

Pros:

  • Saves time
  • Increases supply through double pumping

 Tips:

  • Ensure proper flange size to avoid nipple damage
  • Avoid excessive suction or long sessions to protect tissue

When Should You Pump?

  • When baby sleeps longer stretches or skips a feed
  • After feedings to fully empty the breast
  • To relieve fullness or prevent blocked ducts
  • If returning to work, start 2 weeks before to build a supply
  • Night-time pumping is highly effective due to elevated prolactin levels

How to Store Expressed Milk Safely

Storage Times by Temperature

Environment

Safe Duration

Room Temp (19–22°C / 66–72°F)

3–4 hours

Refrigerator (4°C / 39°F)

3–5 days

Freezer (-18°C / 0°F)

3–6 months

Deep Freezer (-20°C / -4°F)

6–12 months

Label each container with the date of expression.

Storage Containers

  • BPA-free milk storage bags
  • Glass or hard plastic bottles with secure lids
  • Don’t overfill; milk expands as it freezes
  • Single-use bags should not be reused

Thawing and Warming Breast Milk

  • Thaw gradually in the fridge (ideal method)
  • For quick use, place in a bowl of warm water
  • Never use a microwave: uneven heating may destroy nutrients and create hot spots
  • Do not refreeze thawed milk
  • Use warmed milk within 1–2 hours

Breast Milk Management for Working Mothers

  • Start pumping practice at least 2 weeks before returning to work
  • Identify a clean, private space for pumping at your workplace
  • Stick to a pumping interval of every 3–4 hours
  • Use insulated cooler bags with ice packs for milk transport
  • Store milk in the refrigerator immediately upon returning home
  • Create a daily usage plan for frozen and fresh milk rotation
