I do bookkeeping. My mom runs a QuickBooks consulting business, and I get smaller client projects through her. It's hard to find the time, but dh and I are trying to figure out a regular schedule that gives me 10 hours a week. We really need the money.
My committment is to having as much time with my kids and dh as possible. I don't define it in terms of SAHM/WAHM/WOHM. So we try to figure out how I can make the most money while giving up the least amount of family time. For me it is purely financial - I have no intrinsic desire to be working.
I only work when dh can watch the kids. Once I factor in child care, I wouldn't be making enough for it to work for us.
