When Do Babies Nipples Develop

As a new parent, you might have a lot of questions about your baby’s development. One of the common questions is when do babies’ nipples develop? It’s a valid concern because every parent wants to ensure their baby is growing and developing well. In this article, we’ll explore the timeline of nipple development in babies.

When Do Babies Nipples Develop?

Babies’ nipples start developing while they are still in the womb. It’s fascinating to know that nipples and mammary glands form in male and female fetuses, but they only develop further in female fetuses. You can notice small lumps on your baby’s chest, which are the nipples. However, they might not look like the nipples we’re familiar with as they are flat and barely visible at birth.

After birth, your baby’s nipples might appear more pronounced and protruding. It’s due to the hormonal changes that take place in your baby’s body, specifically the estrogen passed from the mother to the baby during childbirth. In some babies, the nipples can even leak milk-like fluid, which is also known as witch’s milk. It’s a harmless condition caused by the baby’s exposure to the mother’s hormones.

Factors That Affect Nipple Development in Babies

Several factors can affect nipple development in babies. Some of these include:

  • Genetics: Just like any other physical characteristic, nipple development can be influenced by genetics. If you or your partner have prominent nipples, your baby is likely to have them too.
  • Hormonal changes: As explained earlier, hormonal changes can affect nipple development in babies. Hormones can be passed from the mother to the baby during childbirth or through breastmilk.
  • Gender: While nipples develop in both male and female fetuses, they tend to develop further in female fetuses because of the presence of estrogen.
