Babysitter Needed for my Children - Now Hiring

Looking for a nanny to care for our 1-year-old boy (in Derwood, MD). Mother works part time and would be home for most of the time that child care is needed (allowing her to run errands and do chores while the nanny helps with baby.) Possibly 2 weekdays, daytime hours, for 4 hours at a time, flexible. No pick ups, drop offs, or pet care needed. May need help with folding laundry or light chores pertaining to the little one. We would prefer a nanny who does not smoke, who is CPR certified and who has college degree.
