How to Express Colostrum Before Birth Safely

A few drops of colostrum can feel surprisingly significant. This first, concentrated milk is often called liquid gold, not because you need to collect lots of it, but because even small amounts can be valuable for a newborn. Knowing how to express colostrum before birth can help you feel prepared for those early feeds, particularly if there is a reason your baby may need extra support after birth.

Antenatal colostrum expressing is not something every pregnant person needs to do. It is a choice, and the right approach depends on your pregnancy, your health history and how you feel. Your midwife can help you make a plan that is safe, practical and right for your family.

What colostrum is and why you might collect it

Colostrum is the thick, golden or clear milk your breasts begin making during pregnancy. It is rich in antibodies and nutrients, and designed in small volumes because your baby's tummy is tiny in the first days of life.

Some families choose to collect colostrum during late pregnancy so it is available if their baby is sleepy, has difficulty feeding at first, or needs their blood sugar monitored. It may be particularly useful when there is diabetes in pregnancy, a planned caesarean birth, a baby expected to be small or early, or a known concern that could make feeding more challenging initially.

It can also offer reassurance. Practising hand expression may help you become familiar with your breasts and with the technique you may use after birth. But it is not a test of your future milk supply. Some people collect several syringes; others see only a glisten of colostrum, even with excellent technique. Neither predicts how feeding will go.

When is it safe to start expressing colostrum?

Many maternity teams suggest starting from 36 weeks of pregnancy, provided your midwife or obstetric team has said it is appropriate for you. Breast and nipple stimulation can release oxytocin, a hormone involved in uterine contractions. For most people at term this is not a problem, but it is the reason not to start early without individual clinical advice.

Please speak with your midwife before expressing if you have had vaginal bleeding, placenta praevia or a low-lying placenta, signs or a history of preterm labour, a cervical stitch, a short cervix, or have been advised to avoid sex or nipple stimulation. If you are expecting twins or more, have a high-risk pregnancy, or simply feel unsure, ask for personalised guidance rather than relying on general advice.

Stop and contact your maternity unit if you have painful or regular tightenings, vaginal bleeding, reduced movements, or anything that does not feel right. You deserve to feel informed and safe, not pressured to carry on.

How to express colostrum by hand

Hand expression is usually more effective than using a breast pump for colostrum. Colostrum is thick and produced in tiny quantities, so it can be easily lost inside pump parts. Before you begin, wash your hands and have a clean, sterile oral syringe or small sterile container ready.

Choose a calm moment when you are warm and comfortable. A warm shower, gentle breast massage or looking at a scan photograph can sometimes help your body relax, but none is essential.

Find the right hand position

Place your thumb above your nipple and your first finger below it, around 2 to 3cm back from the base of the nipple. Your fingers should form a soft C shape. Avoid pinching the nipple itself, as this can be uncomfortable and does not usually move colostrum forward.

Gently press your fingers back towards your chest, then compress your thumb and finger together. Release, then repeat in a slow rhythm. It is a press and release motion, rather than sliding your fingers across the skin.

After a few compressions, rotate your fingers around the breast to reach different milk-making areas. When drops appear, collect them carefully in the syringe. You may find it easiest to express into a clean teaspoon or small cup first, then draw the colostrum up with the syringe.

Try for a few minutes on each breast, once or twice a day to begin with, unless your own midwife has recommended something different. There is no target volume. A tiny bead, or even nothing at all on a particular day, is completely normal. If your breasts feel sore, pause and check that you are not squeezing too hard.

Storing your expressed colostrum

Each syringe should be labelled clearly with your name, the date and the time it was expressed. Follow the storage guidance from your maternity unit, as local arrangements can vary. Usually, colostrum collected at home is frozen as soon as possible and kept in the freezer until you go into hospital.

If you express more than a syringe can hold in one session, use a new sterile syringe rather than topping up a frozen one with freshly expressed colostrum. For hospital birth, take your labelled frozen syringes in a cool bag with ice packs and let the staff know when you arrive. They can advise on storage and use.

It is sensible to ask your maternity team in advance what they provide and what they would like you to bring. This avoids a last-minute search for syringes while you are preparing for your baby's arrival.

What to expect in the first days after birth

Your baby can feed directly from the breast even if you have collected colostrum beforehand. The stored supply is there as a back-up, not a replacement for skin-to-skin contact and responsive feeding where possible.

In the early hours, frequent feeding gives your baby colostrum and encourages your milk supply to build. If your baby cannot feed at the breast straight away, hand expression after birth is often recommended. Your midwife or infant feeding specialist can show you how to protect supply while keeping your baby fed.

For some families, feeding may involve a partner, co-parent, surrogate, intended parent or other support person helping with skin-to-skin, syringe feeds, notes and encouragement. Feeding support should fit your family, not expect your family to fit a narrow script.

A gentle word about pressure

Social media can make antenatal expressing look like another pregnancy task to complete perfectly. It is not. Collecting 1ml can be useful. Collecting nothing can also be normal. And choosing not to express at all does not mean you are less prepared, less committed, or less likely to breastfeed successfully.

The most helpful preparation is knowing who you can call when feeding feels difficult. A trusted midwife who understands your pregnancy, your birth plans and your family can offer practical support without judgement. At Her Village Maternity, that continuity means you have space to ask the small questions before they become overwhelming.

If you are considering expressing colostrum, bring it up at your next appointment. With clear advice and a little practice, you can approach those first feeds feeling supported, understood and never as though you have to navigate them alone.
