Moms who breastfeed their babies know that breast milk changes color.
For instance, colostrum, the first breast milk your body makes, is often orange or yellow because it’s so full of nutrients.
Breast milk also changes color when moms eat certain foods, especially if they have colorful dyes in them — the milk may reflect the color of the food consumed. That means it’s not unusual for breast milk to be tinged slightly blue, green, red, or pink.
But breast milk is actually way more sophisticated than just passing colors through — the saliva from babies’ mouths can indicate to the mother’s body when the baby needs certain antibodies.
One mom, Ashlee Chase, recently documented this incredible color change. When her daughter, Elliot, got a fever, Ashlee nursed her and continued to pump milk as well. When she compared the milk to milk from a few days before, she realized how significant the difference was.
Ashlee shared her photo to Facebook on September 20, 2017, and it got a lot of attention.
