Milk with a bluish colour

Why does my milk look like skim milk?

The appearance of breast milk changes slightly as mothers continue to breastfeed, changing from creamy yellow right after the mother’s milk comes in to a more pale blue, watery appearance that resembles skim milk within several months after birth. This change is normal and not a sign that the milk is low in nutrients. Indeed, these changes reflect the changing needs of the baby.

A) Normal changes in breast milk colour

The appearance of breast milk changes slightly as mothers continue to breastfeed, changing from creamy yellow right after the mother’s milk comes in to a more pale blue, watery appearance that resembles skim milk within several months after birth (Ballard 2013).

Milk can also have other colours in specific circumstances.

B) Reasons for changes in breast milk colour

These colour changes are caused by normal changes in breast milk components and are not a sign that there is a problem with the milk. These changes reflect the changing needs of the baby. Such accommodation is another of the benefits of breastfeeding and is not available to infant formula-fed babies.

C) Unnecessary worries about breast milk colour changes

Some mothers believe that the increasingly blue, watery appearance of their milk indicates that it is not good quality nor able to sustain their baby and will unnecessarily supplement or wean even though their baby is growing normally. Needless concerns about the amount of fat in the milk are especially common.
