Mascardr-
We have two young daughters, and my wife (an over-achieving ex-helicopter chief flight nurse) has taken time to be a stay-at-home mom for a while.
So now her school-day routine is like this: she puts her bike on the rack on her van, drives the kids to school (about 9 miles), then cycles home. At the end of the day, she rides her bike back to the school (where her van is waiting), racks it up, then drives the kids home!
That way, she can have some "down time" by herself, and still do the mom thing.
