She's buying a new, larger vehicle so she can keep babysitting two kids?OT ~ I'm pretty sure that she babysits for the little one and will babysit her little sister when she is born. I recognize her from one of the Gymboree forums that I frequent.
I'd have to do the math on that one. I suspect that increasing the car payment AND paying more at the pump AND paying a larger insurance bill will essentially cancel out the profit from babysitting the kids.
