4 ways Breastmilk changes to meet the needs of your baby

1. It changes within an individual feed:
As the breast empties, the milk becomes progressively higher in fat

2. It changes throughout the day:
As the day progresses, the relative proportion of breastmilk fat and protein increases. So although many are concerned that their supply feels lower in the evening, they can trust that their milk at this time is higher in fat and protein and therefore enough to meet their baby’s needs. In addition, milk in the evening and overnight is higher in melatonin and other hormones which beautifully support a baby’s circadian rhythm.

3. It changes if a baby is exposed to pathogens (germs):
Antibodies specific to these pathogens are produced and transferred to breastmilk to help fight infection. This process is triggered by signals both in a baby’s saliva when they breastfeed, and also from their skin when they are kissed!

4. It changes as a baby gets older:
Not only is the composition of colostrum different to mature milk, but it continues to change to adapt to the needs of a baby as they grow and get older. Amazingly, breastmilk composition is different for a preterm/ premature baby vs a term baby, and also for an older baby/ toddler, if they are receiving less breastmilk in 24 hours. This milk is higher in fat, protein and antibodies, to meet the needs of a busy, and possibly germy toddler.
