Babysitter Needed for my Children

I am currently 9 weeks pregnant with our third child, and stay home with our 2- and 3-year-old. We are looking for someone who can come help with the kids twice a week for a few hours each day while I get some house chores done, go to dr appts, and possibly squeeze in a quick nap! There is a possibility for more hours, once the new baby arrives in April!
