I’ve seen several posts now circulating about blue breast 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 can be many colors. Breast milk can have a natural bluish hue caused by the presence of whey protein (which accounts for 50-80% of the protein content in your milk depending on your stage of lactation). 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 higher whey protein composition which is seen at the beginning of feeding. As the breast continues to empty, the composition gradually increases the casein protein, which is higher in fat, giving it that creamier, white or yellow 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 when you more fully empty 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 whey protein, lower casein 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 and perfect to feed your baby
