Developing breasts is often one of the first signs of puberty for young girls. Breasts start developing at different ages. Some girls start to develop breasts around age 9, others don’t start developing breasts until their mid-teens. This is normal. Everyone is different.
Breast buds developing are the first sign of a growing breast. They look like a small lump under the skin, behind the nipple. It can feel hard to touch and can feel sensitive and tender. As the bud starts to grow, the nipples may start to stick out. Sometimes it can feel itchy as the skin around this area starts to stretch and grow.
It is normal for breast buds to develop at different times. Your child may have one breast bud and not develop their second breast bud for a few months. One breast might be bigger than the other. This is OK
