My 11 yr old daughter showed signs of early puberty (inconclusive tests at 3 yrs old, definite at 5 yrs old) and has been on Depot-Lupron since she was 5 with great results. She also has short parents (5'8" and 5'). Right now she is about 4'11" tall. Hopefully we will be able to keep her on the shots for another year or two. If you have any questions about the shots, please feel free to e-mail me. If you would like to talk on the phone, let me know and we can arrange that as well. Good luck.
