Human breast milk is generally made up of 87% water, 4% fat, 1% protein and 7% lactose.
Breast milk also adapts to the changing needs of your child as she grows. For example, in the first few days after birth, you will produce what is known as colostrum, which is a sticky, yellow-coloured liquid. Colostrum benefits include protecting your baby from infection and helping build their immune system. After a few days your breastmilk will “come in” and will look a lot more like the milk you’re used to seeing.
