Buttermilk for babies: when and how to serve

Q: When can babies eat Buttermilk?

Most babies can start Buttermilk from around 6+ months, as long as they show signs of readiness for solids. Buttermilk itself is a low choking risk because it is a liquid, but it should be served in small, manageable amounts and used in age-appropriate foods. For babies under 12 months, use it mainly as an ingredient in porridges, pancakes, mashed foods, or dips rather than as a main drink. Always supervise cup drinking and avoid serving it with unsafe dippers or chunky mix-ins.

About Buttermilk

Buttermilk is a cultured dairy drink made by fermenting milk with beneficial bacteria. Modern buttermilk is usually thick, tangy, and most often used as an ingredient in foods like pancakes, muffins, mashed potatoes, sauces, and dips rather than offered plain to young babies. It provides calcium for bone and teeth development, protein for growth, potassium for fluid and muscle function, and vitamin B12 and riboflavin to support energy metabolism. Buttermilk can add flavor and moisture to foods, but it is not especially rich in iron, so it should be paired with iron-rich foods as part of a balanced meal. Buttermilk is a common dairy allergen because it contains cow's milk proteins. It should only be offered if pasteurized. Some babies with cow's milk allergy will react even to small amounts in cooked foods. Lactose intolerance is different from milk allergy and is uncommon in infancy, but dairy can still sometimes cause digestive discomfort. Most babies can have buttermilk from 6 months old in small amounts mixed into foods or cooked into recipes, as long as it is not replacing breast milk or formula. From around 12 months, pasteurized buttermilk can also be offered in small amounts in an open cup with meals, while continuing to prioritize a varied diet and close supervision.

How to serve by age

6+ months

Mixed into cooked foods or used in small amounts as an ingredient

Stir pasteurized buttermilk into porridge, mashed vegetables, pancake batter, or other soft foods. Offer only small amounts at first and watch for signs of a dairy reaction.

9+ months

As a dip or mixed into thicker foods

Use buttermilk in dips, soft baked goods, or mixed into mashed beans, potatoes, or grains. Avoid serving with hard or crunchy foods that are not developmentally appropriate.

12+ months

Small amounts in an open cup or as an ingredient in meals

After 12 months, pasteurized buttermilk can be offered in small sips from an open cup with meals, or continued in recipes. It should complement a balanced diet rather than crowd out iron-rich foods.
