What Exactly Does It Mean to Breastfeed Exclusively?

Hey y’all, Kaitlyn here with RF Women’s Wellness, back for another Ask Me Anything. One of the questions I hear often is, What exactly does it mean to breastfeed exclusively? Let’s break it down in a simple, pressure-free way.

What Is Exclusive Breastfeeding?

Exclusive breastfeeding means that your baby is receiving only breast milk as their source of nutrition. No solids, no other liquids—just breast milk. This is generally recommended for about the first six months of life, as breast milk is uniquely designed to meet your baby’s nutritional needs during that stage.

When Do Babies Start Solids?

Around six months, babies can begin what we call complementary feeding. This is when solid foods are introduced in addition to breast milk or formula—not instead of it.

From about 6 to 12 months, breast milk (or formula if you’re supplementing) should remain your baby’s primary source of nutrition, with solids offered after nursing or bottle feeds. At this stage, solids are more about learning than calories.

Why Milk Still Comes First

Think of solids as practice. Your baby is exploring new tastes, textures, and feeding skills, while breast milk continues to fuel their growth and development. Milk is still doing the heavy lifting when it comes to nutrition during the first year.

The Academy of Nutrition and Dietetics defines complementary feeding as anything other than breast milk or formula that’s added once milk alone is no longer enough to meet a baby’s needs. That’s why we always keep milk as the foundation while solids slowly support that transition.

Every Feeding Journey Is Unique

There’s no one “right” way to feed your baby. Whether you’re exclusively breastfeeding, supplementing, or doing a mix, the goal is nourishment, connection, and confidence in your choices.
