Blue Breast milk

I’ve seen several posts now circulating about blue milk having more antibodies for baby when mom or baby is sick. It’s become viral in some circles but it’s not actually based on fact. Breastmilk has a natural bluish hue caused by the presence of casein (which accounts for 40% of the protein content in your milk). This blue hue is usually more visible when the volume of your milk is high and the fat content relatively lower. This can happen for many reasons: You may notice this blueish color more when you’ve has gone a longer time between pumpings, like first thing in the morning, when your breasts are fuller from sleeping longer at night. A blueish tint in expressed breast milk is mainly due to the foremilk composition which is seen at the beginning of feeding. As the breast continues to empty, the composition changes to hind milk, which is higher in fat, giving it that creamier color. It’s a gradual change as the feeding progresses. When using a pump to empty the breast, you may not see the blue color as you’re more fully emptying the breast. Those that use a Haakaa or a milk catcher like a @lacticups may note a more blue color in the milk they collect as these devices often only catch leaking drip milk, which is a higher water content, lower fat content milk.

Be assured, the bluish watery milk and white creamier milk have the SAME components and are the same milk. There are not two different types or kinds of milk. It’s just the ratio of the various components like water and fat that can change based on how you’re feeding and pumping.

Those who feed their babies frequently or empty their breasts often and more thoroughly tend to have thicker milk. Those with an exceptionally robust milk supply or those who go long stretches between feeds tend to have a more bluish hue to their milk.

Regardless of the color of your milk, it is safe to feed your baby
