Just like everything else in motherhood, breastmilk can come in all sorts of colours—and for the most part, it’s all perfectly normal. Many mamas won’t even notice breastmilk colour if they don’t pump - but for those that do, let’s chat through them!
Yellow-ish or Golden
Often the very first milk you produce, known as colostrum, can be thick, sticky, and golden or even a deep yellow. It’s packed with nutrients and antibodies that give your baby’s immune system a boost right from the start.
Bluish or Thin
As your mature milk comes in (around day 3–4), some mums notice their milk looks a bit bluish or watery—especially at the start of a feed. This “foremilk” hydrates your baby and is perfectly normal. The milk gets creamier as the feed goes on.
Greenish Tint
Eating a lot of leafy greens and taking certain vitamins can occasionally give milk a slightly green tint. It’s usually nothing to worry about, but if other symptoms pop up, have a chat with your midwife or doctor.
Pink, Red, or Rusty
Sometimes you may spot pinkish or rusty-coloured streaks in your milk, commonly from small amounts of blood. This can happen if you have cracked nipples or a broken capillary in the breast. Often, it’s not harmful for bub, but if the bleeding is ongoing or painful, seek advice from a GP or lactation consultant.
Very Rare or Unusual Hues
Certain medications, foods, or supplements can lead to less common colours like orange or even black. If it’s an ongoing change or if you’re worried, talk to a midwife or GP to see if medication or diet adjustments are needed.
When to Seek Help
Most colour variations are harmless and temporary. Still, trust your instincts:
● If you see frequent or large amounts of blood in your milk,
● If you have painful or cracked nipples,
● Or if you’re simply concerned about the colour,
Please reach out to a lactation consultant, midwife, or GP for a chat.
