Expressing your breast milk
Expressing your breast milk
Expressing your breast milk can be a helpful skill to learn in the early days of having a baby.
If you are separated from your baby or your baby is reluctant or unable to breastfeed it is important to ideally:
- start expressing within 6 hours of birth;
- express 8-10 times in 24 hours;
- express once at
This will help to stimulate and maintain your milk supply.
All breast milk collected is beneficial to your baby. Initially the volume of colostrum (the thick, rich early milk in the first few days) can be as little as 1ml but will increase as you continue to express regularly. The most appropriate method of giving your breast milk to your baby will be discussed with you at the time.
Before you start
- Wash your hands
- Ensure any equipment for collecting and storing your breast milk has been washed in hot soapy water and sterilised immediately before
- It is helpful to have a clean, damp cloth and dry tissues close by in case there are accidental splashes or spillages of milk which can occur particularly with hand
To encourage your milk to flow:
- Find a warm, comfortable and relaxing place to
- Hold your baby ideally with skin to skin contact, have baby nearby or have a photo of baby which you can see.
- Apply warm flannels to your breasts or have a warm
- Gently massage all areas of your breasts being careful not to slide your fingers along the breast as this can cause skin damage – see below. Spend a few minutes massaging the breast/s before moving on.
- Cup your breast and make a ‘C’ shape with your thumb and
- Place your thumb and finger on opposite sides of the nipple, 3-4cm apart, or where the texture of the breast tissue feels
- Without sliding your fingers over the skin, gently squeeze your thumb and finger
together. This shouldn’t hurt. Release the pressure and squeeze again and again, building up a rhythm.
- You may only see a few drops at The more you practice, the more colostrum will start to appear.
- Once the flow of colostrum has slowed down, rotate your fingers round to try a different part of the When you have tried all parts of one breast, repeat the process on the other breast.
- Expressing from both breasts at the same time, whether by hand or pump, is said to increase milk volume and reduce the time taken. Pause for 30-60 seconds when the milk flow slows down to allow the ducts to refill.
Expressing using a manual or electric pump
- It is useful to hand express prior to using an electric pump as it may reduce the time it takes for the milk to start
- Correctly assemble all sterilised
- Support your breast if
- Place funnel centrally onto nipple and
- Ensure suction dial is turned to its lowest setting if
- Switch on and increase suction gradually to the maximum comfortable level. If it is uncomfortable then the suction is too high.
- Some pumps have ways of varying the speed, this tries to mimic the way a baby feeds— quick sucks at the start of a breastfeed followed by slower sucks as the milk flow increases and the baby settles into a breastfeed. Some dual phase pumps do this
- Swap breasts each time the milk slows This allows the milk ducts to refill with milk.
- Always remember to switch the pump off before removing the funnel from your
- Stop after 20-40 minutes or when the milk stops

|Fridge: 5-8°C||Can be kept at the back of a fridge for up to 3 days|
|Fridge: 0-4°C||Can be kept at the back of a fridge for up to 5 days|
|Ice compartment||Can be stored in an ice compartment of a fridge for 2 weeks|
|(if temperature rises above 4°C||after 3 days, use within 6 hours or throw away)|
|Freezer: ¯ 18°C or lower||Can be stored in a deep freezer for 6 months|
|Previously frozen breastmilk|
|Defrosted in fridge||Defrost in the fridge for 12 hours. Use as soon as possible after thawing|

Using stored breast milk
- Ideally defrost frozen breast milk in the fridge. If needed quickly try defrosting under cool, then warm, running Thawed milk warmed to room temperature must be used straight away or discarded.
- Milk may be warmed to body temperature by standing the container in warm water for a few minutes. Do NOT use a microwave to defrost or warm breast milk. It is heated unevenly and could burn your baby’s mouth.
