Colostrum is often called “liquid gold”, and for good reason, this thick, golden fluid is the very first food your breasts produce, sometimes from as early as 16 weeks of pregnancy, and during the first few days after birth. Although small in volume, every drop is packed with powerful nutrients and antibodies specially designed to protect and nourish your newborn baby, whether you choose to go on to breastfeed or formula feed.
What Is Colostrum?
Colostrum is a concentrated, nutrient-rich pre-milk that your body produces before your mature milk comes in. You’ll only make tiny amounts, sometimes just a few millilitres at a time, but that’s exactly what your baby’s tiny stomach needs in those early hours and days.
Why It’s So Important
- Immunity Boost: Colostrum is full of your antibodies (in fact it is a personalised medicine for your baby) that help to line your baby’s gut and defend against infections and kickstarting their own immune system.
- Supports Gut Health: It helps develop your baby’s digestive system, sealing the gut lining and reducing the risk of allergies and tummy upsets.
- Nutrient-Dense: Rich in protein, vitamins A and E, and minerals, it provides everything your newborn needs before your milk proper “comes in.”
- Acts as a Gentle Laxative: Colostrum helps your baby pass their first stool (meconium), which aids in clearing excess bilirubin, which in turn helps to prevent jaundice.
When and How to Express Colostrum
Some people choose to hand express small amounts of colostrum in the final weeks of pregnancy (from 37 weeks gestation) particularly if their baby might need extra support at birth (for example, if they have diabetes or are having a known premature or unwell baby), however, we now know that all babies benefit from receiving early colostrum.
After birth, your baby will naturally root to seek the breast. Frequent skin-to-skin contact, and responsive feeding help your baby access as much colostrum as they need. If you have harvested stores of colostrum your baby does not even need to awake for you to give it to them, simply pop the syringe under their tongue and they will simply absorb it through their mucous membranes – how incredible!
In Summary
Colostrum may come in tiny amounts, but its impact is huge. It’s nature’s first vaccine, a personalised medicine, a protective shield, and the perfect start for your baby’s lifelong health.
