Nanny Needed For My Children - Full-time / Part-time

We are looking for a sitter to help with morning drop off (7:00am-8:30am)& afternoon pickup (3:30pm-4:30pm) 2 to 3 days per week for 1 child in Kansas City. Older sister will be home in the afternoon, so we probably will not need any care provided after drop-off at home. We would prefer someone who has their own car and who does not smoke.
