Hi there, my daughter just turned 9 years old. i recently noticed changes in her body. shes developing lumps on both her breasts. they are visible to the eye. is this normal for a 9 year old?

Normal: 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. Coarse hair may also appear in the pubic areas or under the arms. Most girls get their first period within 2-3 years after the development of breast buds. All of this is normal and should be discussed with the child
