Childcare Needed - Full-time / Part-time

We are looking for a great nanny for 2 children in Springfield. We would prefer someone who could help out with light housekeeping. We would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets and who is CPR certified. Husband has job that requires attendance to night meetings. Looking for assistance with the kids for the evening and bedtime routines, including after daycare activities, assistance with kids during dinner time, cleaning up, bath and bedtime routines. These will occur infrequently but maybe be 1-2 times per week at most, or may not occur for several weeks.
