Babysitter - Full-time / Part-time

Hi! we are a family with two working parents, with two small children. one child is 5 years old and another is 9 months old . we're looking for someone who could help with getting kids ready for school/daycare and do drop off and pickup. We would prefer someone who does not smoke, who is comfortable with pets and who is CPR certified. This wouldn't have to be every day, looking for someone who is flexible with schedules and not expecting full time work.
