Nannies work, if done right. My parents had to do it because my mom, and dad were working. My dad was in the Navy, so he'd be underway on a regular basis, and my mom would be the one working. When my mom got home, it was just us kids, and her. It also helps to have a Nanny who can set the kids straight.
I gave my nefew (15yr old) my old pearl 8130.. 3 months later $700 phone bill.... So in my experience I'd say no for a job-less teen with a bb (unless its pay as you go)
