Breast buds can feel sore or tender. They can also feel like nothing at all, to the point where you forget they exist… that is, until someone or something bumps into them and then OOF! 

Breast buds are the small, firm bumps that appear under the nipples when boobs first start to grow. They are usually about the size and shape of a stack of 4 or 5 dimes. They can feel especially tender when something pushes up against them - someone’s backpack, an elbow - or super sensitive with certain pieces of clothing. This change in sensation happens because the nerves in the area are stretching, which really just means you are growing.
