Breast milk is generally considered to taste sweet and creamy and have a pleasant flavor. However, when it comes to taste, everyone has a different experience. Your taste is developed over time depending on your genetics, your culture, and the foods that you're exposed to throughout your life. Breast milk is like any other food, and it may taste different to different people. 

Breast milk contains the milk sugar lactose.

Even though lactose is not the sweetest type of sugar, when there is a large amount of lactose present, the sweetness is much greater. Since lactose is one of the main ingredients in breast milk, it appears in high concentrations giving breast milk its sweet flavor.

Breast milk also contains fat. The amount of fat in milk determines it's creaminess. When breast milk first starts to flow from the breast, it has less fat so it may appear thin and watery. But, as the milk continues to flow, it becomes higher in fat and much creamier.

What Contributes To The Taste Of Breast Milk?

Beyond sweet and creamy, breast milk is also flavored by the foods that you eat every day. By eating a well-balanced diet full of fruits and vegetables, you are exposing your child to the tastes of these healthy foods. As your breastfed child grows and begins to eat solid foods, it is believed that he will more readily accept the foods that he has already been exposed to through your breast milk.

In this way, your child can develop a taste for many of the foods that you enjoy, even garlic, spicy foods or other cultural dishes.

What Affects Breast Milk's Taste

Hormones: Changes in your body from the return of your period or a new pregnancy may influence the flavor of your milk. It is still safe to breastfeed if you have your period, and it's usually safe to continue to breastfeed if you become pregnant again as long as you are not high risk.

So, if you still want to breastfeed continue to offer your child the breast.

Exercise: The build-up of lactic acid in your body along with the saltiness of perspiration on your breasts from strenuous exercise can interfere with the taste of your breast milk. When you exercise, keep it at a light or moderate level and wash your breasts to remove any sweat before you feed your baby.

Medications: Certain medications can change the taste of your breast milk. If you start a new medication and notice your child is not breastfeeding as well, that might be the cause. Talk to your doctor if you think this is an issue.

Smoking: Studies show that the breast milk produced after a mother smokes cigarettes will take on the smell and flavor of the smoke. If you smoke, have your cigarette immediately after you finish feeding your child and try not to smoke for at least 2 hours before breastfeeding to keep the smell and flavor of the smoke at a minimum.

Alcohol: Consuming ​alcohol is known to affect the flavor of breast milk.

It takes about two hours per drink for alcohol to leave your body and your breast milk. The longer you wait after you have an alcoholic beverage, the less alcohol will be in your breast milk.

Frozen Breast Milk: Breast milk that has been collected and stored in the freezer will sometimes have a soapy odor and taste when it's defrosted. It is still safe to give this milk to your child; however, your child may not like the taste and refuse it.

Mastitis: A breast infection can cause the milk in your affected breast to have a strong, salty taste. And while it's still safe to breastfeed from both breasts during this time (both the affected and unaffected) if you think you may have mastitis, see your doctor for treatment.

Body Products: Lotions, creams, soaps, perfumes, oils or ointments that you put on your breasts can add different flavors to your milk as your baby nurses. If you use any body products on or near your breasts, be sure to wash your breasts well before breastfeeding your baby.

A change in the taste of your breast milk for any of these reasons may affect your child. Some babies will not seem to notice or mind the variations of taste while other children will nurse less, go on a nursing strike or even appear to be self-weaning. By understanding some of the things that can change the flavor of your breast milk you may be able to keep your child nursing longer.

Is It OK To Try Your Own Breast Milk?

If you are concerned about the flavor of your breast milk, or you just want to know how it will taste to you, you can try it. Breast milk is a natural, healthy food, and it will not hurt you. There is nothing wrong or disgusting about trying your own breast milk.

Is It OK To Taste Someone Else's Breast Milk?

Sometimes husbands or partners are curious and want to taste breast milk as well. It is OK for them to try it too, as long as they know the health history of their partner and understand the risk involved. Always be smart and use common sense because it can, of course, be dangerous to try the milk from another person's breast. Breast milk is a body fluid. Therefore, it is possible to contract an infectious disease, including HIV, from ingesting someone else's breast milk.
