can a petit girl of 9 (only turned 9 in jan) be developing (breasts)? she just said to me that one of her nipples hurt when she touched it, had done for the last few days. i told her to lift up her nightie. her nipple didn't look like a little girls nipple, the other one looked the same as the other one. when i touched it it actually felt swollen/lump, they both did, i can't believe that she may well be developing. i am totally freaked out. should i go to dr? if she is developing early then i feel ridiculous. she is only small/skinny too so the last type of kid that i would have thought would develop early. anyone else know of a petit/small i height 9 year old that has started to develop breasts?
