The estrogen in the mother’s blood can reach the baby through the placenta, causing the development of breast buds. Breast buds are small disc-shaped lumps felt under the nipple and areola (a small circular dark area surrounding the nipple).
Why does my 2 year old daughter have breasts?
Baby girls (and boys) often have breast buds (thelarche). In girls, these grow bigger during the first 6 to 18 months of life, but are usually regressing (growing softer) by 2 years of age.

Baby girls and boys will have a small breast bud that can be felt for a few weeks after they are born. These buds of tissue will become the breast tissue in the adult. In early infancy, they can be prominent because of the effects of the mother’s estrogen. As the estrogen levels decrease, so does the prominence.

Breast buds tend to go away gradually by 6 months of age, but they can last longer in some babies. In preteen boys, gynecomastia can also be caused by an estrogen-producing tumor. Breast buds are common during puberty. The buds may last up to 2 years, but they tend to go away within the first year.
What does a breast bud look like?

What age does breast buds start?
Girls usually begin puberty between the ages of 8 and 13 years old. The earliest sign of puberty in most girls is the development of breast “buds,” nickel-sized bumps under the nipple. It is not unusual for breast growth to start on one side before the other.
What causes early breast development?
It’s just like normal puberty, but it happens early. The pituitary gland starts making hormones called gonadotropins. These hormones cause the testicles or ovaries to make other hormones: testosterone or estrogen. These sex hormones cause the changes of puberty, like breast development in girls.
Are baby breast buds normal?
