As strange as it sounds, noticing a "rainbow" of colors when you pump or examine your breast milk is totally normal. Though your milk won't be a literal rainbow, it's not uncommon for it to be tinged with different colors like blue, green, or even pink. Aside from staring at your nutritional artwork in awe, knowing what different colors in your breast milk mean can be helpful as you examine your diet or even simply to understand why in the world your milk isn't purely white.
Obviously, the food you eat has a huge impact on the contents of your breast milk. And, as it turns out, your food intake impacts the color of it as well. The majority of the colors your milk may turn will be dictated by what foods your diet is rich in, according to La Leche League International (LLLI). This doesn't mean anything is wrong with your diet or your breast milk, and, in the vast majority of cases, noticing an odd tinge in color to your milk is nothing to worry about.
Sometimes, your milk will be colored by other things besides food, but even then, it's usually harmless. So, pump and nurse on, knowing that your breast milk's color can be just as unique as the baby you're feeding it to.
1Your Breast Milk Is Clear-ish Or Blue
According to Very Well, when your milk first lets down, it may be clear or blue-ish, signaling that it is the "fore-milk." After you continue nursing or pumping, your milk will thicken and whiten and is termed "hind-milk."
2Your Milk Is Green
A green tint to your breast milk is a sign that you've consumed lots of green vegetables like spinach or seaweed, or green colored drinks, according to LLLI.
3Your Milk Is Orange Or Yellow
LLI noted that diets high in carotene, which comes from vegetables like yams, squash, and carrots, will turn your milk a yellow or orange color. Similarly, frozen breast milk may have a yellow appearance.
4Your Breast Milk Has Blood In It Or A Rusty Brown Color
According to Infant Risk, having a small amount of blood in your breast milk is normal and harmless to baby. It is generally caused by two things: either a small rupture in a blood capillary, cracked nipples, or the presence of a (generally harmless) bacterium called Serratia marsescens.
5Black-ish Breast Milk
No, it's not from drinking too much coffee. As scary as it sounds, black-ish breast milk shouldn't cause you to worry. It's caused by some medications or a hint of blood staining in your milk, according to an article from Bundle Organics. Speak to your doctor to make sure your medication is safe for breastfeeding.
