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

We are looking for a sitter for our 2-month-old baby in Silver Spring. I work as a nightshift nurse and need to leave home at 5 p.m. and my husband gets home at 6 p.m. So, we only need someone to watch our baby during the time that I have to leave and when my husband gets home. There are times that my husband has to work a little late but that would be communicated with the sitter early that day. My work schedule alternates, every Monday, Thursday, Friday and every other Wednesday. We have one dog that is a beagle but he will be in his crate during the time that I have to leave for work. We would prefer someone who has their own car, who is comfortable with pets and who is CPR certified.
