Cell phones for kids

Many kids now days want cells phone. My 10 year old wants
a cell phone real bad. But she hardly leaves the house. I
told her if she does all her chores and saves her money she
can buy herself a prepaid phone to start out. Then once
she gets a little older and she has more sleep overs and
things then I would put her on my cell plan. I want to teach
my child responsibilty. And how to work and earn what she
wants. I don't just hand my child everything. She works
hard to get those things she wants. And by doing this
it is really paying off, she has the up most respect for
me, she sees how hard I work to get the things she needs
and she values it now. She also has respect and manners.
I think some parents are slacking on teaching their
certain things like this in life.
