That started in Julia at around the same age.  She also had slight pubic hair.  After having LHRH tests for over a year to determine if she was experiencing precocious puberty, it finally came back as a yes.  She is now on LUPRON DEPOT monthly injections which have slowed down the breast growth, but for some reason the pubic hair is still coming in (although they say she is under control).  She is now 8.5 years old and hopefully we can hold off on puberty for a few more years.
