Introduction
To understand breastfeeding, it helps to know a little about how the breast is built inside. Don’t worry — we’ll keep it simple and practical.
1. Main Parts of the Breast
-
Lobes and Lobules
-
The breast is like a bunch of tiny “milk-making factories.”
-
Inside, there are 15–20 lobes, and each lobe has many smaller parts called lobules.
-
These lobules contain tiny cells that make breast milk when the baby suckles.
-
-
Milk Ducts
-
These are like small pipes or tubes that carry milk from the lobules to the nipple.
-
They join together under the areola before opening at the nipple.
-
-
Nipple
-
The tip of the breast where milk comes out.
-
It has many small holes (not just one) where milk flows.
-
It also has nerve endings — when baby suckles, signals travel to the brain to release milk.
-
-
Areola
-
The darker circle of skin around the nipple.
-
It has small bumps (called Montgomery glands) that make oils to keep the skin soft and give off a smell that helps guide the baby to the breast.
-
Babies need to latch on to the areola, not just the nipple, to get enough milk.
-
2. How It All Works Together
-
Baby suckles → nerves in nipple/areola send signals to the brain → hormones released → milk made and pushed through ducts → milk flows out of nipple.
-
It’s a teamwork system between baby, brain, and breast.
End of Lecture Quiz
Q1. The breast makes milk in:
A. The nipple
B. The areola
C. The lobules inside the breast
D. The ducts
Answer: C. The lobules inside the breast
Rationale: Lobules are the tiny sacs where milk is produced.
Q2. Why should a baby latch onto the areola, not just the nipple?
A. Because the nipple alone has no milk
B. Because the areola looks darker
C. Because it allows better suction and milk transfer
D. Because it prevents milk from being made
Answer: C. Because it allows better suction and milk transfer
Rationale: A deep latch on the areola helps the baby press the milk ducts and get more milk.
Q3. What do Montgomery glands in the areola do?
A. Make milk
B. Keep the skin soft and release scent for the baby
C. Block the ducts
D. Store milk
Answer: B. Keep the skin soft and release scent for the baby
Rationale: They produce oils and smells that protect the skin and guide the baby.

Key Takeaways
-
Lobules make milk, ducts carry it, areola helps baby latch, nipple releases milk.
-
A baby needs a deep latch on the areola, not just the nipple, for effective feeding.
-
The breast is designed perfectly to make, store, and deliver milk for the baby.
Call to Action
-
Mothers: Trust your body — your breast has all the structures needed to make milk.
-
Health workers: Use simple terms (“milk tubes,” “milk factories”) when teaching mothers.
-
Communities: Encourage positive messages about breastfeeding anatomy and function.
