Colostrum, the yellowish ‘first milk’ produced from the second trimester of pregnancy is an antibody rich immune booster and has often been called ‘baby’s first immunisation’.
Colostrum helps to activate early immunological responses in your baby's gut, promoting the development of normal gut flora and preventing the growth of harmful bacteria. It also increases peristalsis, helping the newborn to pass meconium. This reduces the reabsorption of bilirubin and the potential to develop jaundice if bilirubin levels become elevated.
In perfect circumstances, colostrum should be every newborn’s first feed, however there are medical conditions and issues for some mothers and babies that may mean infant formula is offered to newborns. For instance, babies of mothers with diabetes are particularly at risk of hypoglycaemia (low blood sugar) in the first few hours after birth so although colostrum can be useful in this period to stabilize your baby’s blood sugar levels, these babies are often given formula.
One way to see that your baby is less likely to be offered formula in this important newborn period, is to express and store colostrum during the last weeks of pregnancy. Discuss this with your health- care providers and write a post birth plan (see below) so that everyone caring for you knows your wishes – before your baby is offered formula as his first feed.
In the sixties and seventies – mothers were advised to express colostrum during late pregnancy, supposedly to unplug milk ducts and increase the production of colostrum. There was also evidence that women who expressed during pregnancy were more confident with breastfeeding but despite this, advice about antenatal expressing was abandoned, possibly due to concerns that nipple stimulation could cause early labor. However, recent studies including a study of women who breastfed through pregnancy( Moscone and Moore 1993), show that uterine contractions will only occur following the up-regulation of oxytocin binding sites in the uterus, when your body is ready to begin labor. This means that nipple stimulation won’t induce labor unless you are at term.
If you have a history of premature labor, prenatal expressing may be contra-indicated and if any cramps do occur while you are expressing colostrum, stop and discuss this with your health professional.
To express colostrum:
Please don't worry if you only get a 'glisten' of colostrum, this is no indicator of how your supply will be postnatally - as your placenta is released, your postnatal hormones will trigger your lactation.
Here is a great link to a video on massage and hand expression - this technique is very effective whether you are expressing colostrum or you need to express after your baby is born. Most importantly, write a post birth plan that includes uninterrupted skin to skin cuddles as soon after birth as possible, delayed weighing, delayed bathing so baby keeps his amniotic smell longer (and don’t wash your own chest the first day so baby follows this amniotic smell back to the breast and latches more easily), and advise (pop a notice on your baby's cot if he is in a nursery) “Colostrum in freezer for baby if needed.”

Liz's story of expressing colostrum to nourish her newborn
In preparation for the birth of our son a year ago I hand expressed colostrum. When we went into hospital I took in the expressed 150 mls. This was lucky as he weighed 4.6 kilograms and had low blood glucose levels. He breast fed and then needed top ups. Instead of giving him formula, the staff were able to give him my expressed colostrum.
I wanted the best for him and if I hadn't had enough expressed breast milk formula would have had to bridge the gap. I was told by one of the staff that they would have to give him formula as they were getting low in my milk and his blood glucose levels were borderline. I was a little worried and expressed a few mls and then tried on him on the breast. He breast fed really well from both sides and continued to do so and has not stopped breast feeding since.
He's been a real champion and I am so proud of him. When I'm holding my baby boy in my arms I feel so content and in love and love the hormonal changes that occur. It's such a lovely content feeling. I love it when we look at each other when he's feeding and he smiles. Pure bliss.
Liz is a fan of Boobie Bikkies too! I love breast feeding my little boy. At Christmas time we went to see my husband’s family which is a little stressful. I was worried about the effect of the stress on my supply. I purchased a box of Boobie Bikkies and took them with me and they worked perfectly. I was so thrilled as was my son.
