Babysitter

We are looking for a mothers helper starting in mid-November. I am due with our third around Thanksgiving and looking to get my little boys (4 and nearly 2 yrs old) used to someone new before we have another baby. This would be part time (around 10-20 hours a week)? during the week and possibly some times on the weekend if that worked for everyones schedules. We anticipate needing this support through December and possibly January as well. We would be happy to have a homeschool teenager or similar.
