If you're preparing to breastfeed, you may have heard the word colostrum and wondered what it actually is.
Colostrum is your baby's first milk. Your body starts producing it during pregnancy and it is the milk your baby receives in the first few days after birth, before your mature breast milk starts to increase.
It may look quite different from the milk you were expecting - and that's completely normal.
What does colostrum look like?
Colostrum is usually thicker than mature breast milk and can be yellow, golden, creamy or even slightly clear. It can also be quite sticky. There isn't one particular colour or consistency that your colostrum has to be. Everyone is different. And don't be surprised by how little there seems to be. Colostrum is produced in small amounts, but that's exactly what your newborn needs.
Is colostrum enough for my baby?
Yes. Your newborn's stomach is very small in those first few days, so they don't need large amounts of milk at each feed.
Colostrum is particularly concentrated and contains nutrients and other components that help support your baby during those early days.
Your baby may want to feed frequently, which is completely normal.
Those frequent feeds also help your body receive the signal to keep producing milk.
Why is colostrum important?
Colostrum is sometimes described as "liquid gold", and there's a good reason it gets so much attention.
It provides your newborn with important nutrients and contains antibodies and other protective components that support their developing immune system.
It is also specially suited to your baby's tiny digestive system. So although you may only see a few drops at a time, those drops are incredibly valuable.
When does colostrum change into breast milk?
Your body doesn't suddenly switch from colostrum to mature milk overnight. Your milk gradually changes over the first few days as your baby's needs change. Many mums notice their breasts becoming fuller around 2–4 days after birth, although this varies from person to person.
Your breasts may feel heavier, firmer or warmer, and you may notice that you're producing more milk. This is often referred to as your milk "coming in".
How often will my baby feed?
Newborns usually feed little and often. In the early days, your baby may want to breastfeed frequently - sometimes 8–12 times in 24 hours or even more. There may also be periods when your baby wants to feed repeatedly over a shorter period of time. This is known as cluster feeding.
It can feel as though you're feeding constantly, but frequent feeding is normal for many newborns. Try not to compare your baby's feeding pattern with someone else's. Every baby is different.
Can I express colostrum before my baby is born?
Some mums choose to express and collect colostrum during pregnancy, particularly if their midwife or maternity team has recommended it. However, antenatal colostrum harvesting isn't suitable for everyone or at every stage of pregnancy. If you're considering expressing colostrum before your baby arrives, talk to your midwife or maternity team first so they can advise you based on your individual circumstances.
What if I'm worried that I'm not producing enough?
It's very common to worry about milk supply, especially when you're only seeing tiny amounts of colostrum.
Remember that your newborn's stomach is tiny and colostrum is produced in small, concentrated amounts.
If you're worried about whether your baby is feeding effectively, their feeding pattern, nappies or anything else, speak to your midwife, health visitor or breastfeeding support team.
You don't have to work it all out by yourself.
Your baby's first milk
Those first few days can feel like a lot to take in. You're recovering from birth, getting to know your baby and learning how feeding works - all at the same time. Try not to worry about how much milk you can see.
Colostrum is exactly what your newborn is designed to receive in those early days. And as your baby grows and their needs change, your milk will change with them.
