Runners- how often do you take rest days?

This is what my schedule currently allows:
MWF I do a Jillian Michaels DVD
Tuesday is "rest day" but I typically take my daughter out in her stroller for a walk.
Thursday I do a 3 mile run
Sat and Sun I do a 6mile run in the morning and a 6mile run in the afternoon, each day.

I'm hoping to up my Thursday run to a 6 mile as well.
