Part-time In-Home Nanny For 5 Month-Old Baby Boy

My husband and I are expecting our first child at the end of April. I will be retuning to work in September and we are looking for someone to come to our home to provide child care approximately 3 days per week while I work from home in our basement office. This would be approximately 2-3 week days every week but the week days would change occasionally so we need someone who is flexible. Must be comfortable with pets as we have 2 very friendly and well mannered dogs. Has to have reliable transportation and a clean background with no previous arrests, criminal involvement, or DCFS involvement. Must be CPR certified but we are willing to pay for the certification class for the right candidate. This would be an ongoing position so we need someone who is able to commit to the job for at least 1 year at minimum.
