Bare in mind that boobs can grow up to the age of 21.

Sure girls enter puberty a few years younger then boys, but puberty doesn't end when you leave your teens and you can actually change a bit up to the age of about 21. You also get late bloomers who don't mature as soon as everyone else.

Basically you don't hit 12 and suddenly have boobs and periods and then thats the end of it.
