Great question Clara, I've wondered the same thing and it's one that hopefully some GG's will chime in on.

Curious, did you ask your SO if she remembered when her soreness went away?

I did ask her. She said that she doesn't remember her breasts ever being sore before, during, or after puberty. But that's just her experience. There are guides for young girls that do warn of breast soreness during puberty.
