Mothers start to produce colostrum (early milk) while pregnant. Being able to express colostrum is a useful skill to have. Saving you expressed colostrum may also be beneficial if your baby is likely to need special care after birth.
Breastmilk is a complete and perfect food for your baby. If the unexpected happens and you and your baby are separated, or if your baby has feeding difficulties or health problems, you will find it easier to express your milk for your baby if you have practised beforehand.

Expressing during pregnancy
Being familiar with your breasts and how they work will give you confidence for after the birth.
- You’ll be able to express a small amount of colostrum onto your nipple if your baby needs encouragement to feed.
- You’ll be able to express colostrum for your baby if he has difficulty feeding or is cared for in the neonatal intensive care or special care baby unit.
- Being able to hand express will help you avoid problems with engorgement and mastitis.
If your baby doesn’t breastfeed well in the first few days, being able to hand express will help you:
- Express your milk if needed.
- Provide your own milk for your baby to prevent or treat conditions such as low blood sugar or jaundice.
- Avoid the need to give infant formula.
You can start expressing in your third trimester with the support of your midwife.
Is it Safe
Don’t worry – following the suggestions to express for a few minutes each day is unlikely to trigger labour. Check with your midwife if you are at risk for early labour. If you experience any uterus cramps when expressing, stop immediately and contact your midwife.
Learning to hand express while pregnant, and collecting and saving the colostrum can be helpful in some special situations, including:
This is sometimes diagnosed during pregnancy. Babies with any form of cleft can find it harder to breastfeed. Breastfeeding is particularly important for the first six months as it helps protect these babies against ear and respiratory infections. When the cleft is repaired, your milk helps promote healing and protects your baby against hospital germs.
In the first 24 hours after birth, babies of diabetic mothers risk developing low blood sugar levels (hypoglycaemia). A baby needs colostrum to maintain his blood glucose levels. Exclusive breastfeeding has been shown to reduce the risk of a baby developing diabetes later in life.
Mothers with breast abnormalities or who have had breast surgery
Stored colostrum can be helpful if you encounter problems establishing milk production.
Some medical conditions may make it harder for you and your baby to establish breastfeeding. Or, if you need to start medications that are incompatible with breastfeeding immediately after birth, your saved colostrum can still be given to your baby.
Some NHS hospital trusts already have policies in place for sharing information on antenatal expression. Your midwife and other members of your antenatal care team may have information to share on breast massage and how to hand express. They should also be able to give you small sterile bottles, syringes or other containers with identity labels in which to save your colostrum.
Do ask if the hospital has an Infant Feeding Specialist who will be well informed about breastfeeding and a source of support in those early days.
Hand expression is the best way to express colostrum. It is simple to learn and gets easier with practice. You’ll only be expressing small amounts of colostrum, so using a pump will be impractical and may not be as effective.
You may receive information and a demonstration on hand expression from your midwife. Hand Expression of Breastmilk gives information on an effective technique.
Antenatally, you’ll only need to express for three to five minutes—just until you have a few drops of colostrum. It may not seem very much, but a baby’s first feed is no more than a teaspoon of colostrum. By expressing up to three times in a day, you can express enough for a feed. With practice and regular stimulation, you’ll be able to express more colostrum.
When you go into labour
Take your stored colostrum with you to the hospital in a cool bag. The hospital can arrange to keep your colostrum frozen, possibly in the special care baby unit. Make sure you or your birth partner makes a note of where it is stored and that details are in your notes.
If you and your baby are likely to have difficulties or be separated, one of the containers can be defrosted once you’re close to birth. This is then ready for the first feed, if needed.
Your baby will need to breastfeed at least 8–12 times in 24 hours. If, for any reason, you are separated or unable to breastfeed your colostrum can be defrosted if needed, one container at a time to avoid waste. Your colostrum can also be used if your baby needs supplements.
The first few days
Frequent breastfeeding and keeping your baby close by will help establish your milk supply and get breastfeeding off to a good start. If you and your baby are separated, express milk eight times in each 24 hours including once at night, until your baby is able to breastfeed.
Expressing as well as breastfeeding is important if your baby isn’t feeding well, or needs supplements for any reason. This will help establish milk production and provide milk for your baby’s next feed if needed. For any problems, seek skilled help from an LLL Leader with our list of local leaders
A handy technique
Hand expression is a useful technique to learn even though most mothers find they rarely need to express and store their milk.
Hand expression is effective, convenient and free. You may also find you can express more milk by combining hand expression with pumping than using just a pump.
1 It helps to be warm and relaxed.
2 You could practise in the bath or shower at first. When you start collecting colostrum, express after a bath or shower.
3 Wash your hands.
4 Massage your breasts to help milk flow.
5 Hand express from both breasts. Take care NOT to cause pain or discomfort.
6 You are likely to see small droplets or drips of colostrum appear as you express. Express directly into the container so you save every precious drop. If you’ve been given syringes and find it difficult to collect your colostrum, express into a small clean container (eg cup) and draw the colostrum up into the syringe.
- You can express up to three times in the same day.
- If you plan to express again that day, store the syringe in the coldest part of the fridge. This is usually at the back.
- Once you’ve expressed for the last time that day, seal the syringe in a bag. Label and date it before placing it in the freezer.
- The colostrum could be kept in the fridge if you’re going to be induced or have a planned caesarean section within a day or two. Fresh colostrum inhibits the growth of bacteria and can be safely refrigerated for 48 hours.
