Babysitter Needed for my Children

My husband and I have different schedules one week is mornings for him and then the other its morning. Then I work overnight 2-3 day out of the week and on call. We are looking for someone to watch them for a couple hours at night until dad gets home one week and then in the morning to stay in the house until they need to get up for school and help until I get home. Schedule will be known in advanced unless I get called in.
