Part-Time Nanny Needed For 2 Children

We are looking for a part-time nanny for our baby (4 months) and toddler (3 years) starting in January, throughout the year. The hours are flexible and might change each week depending on my wife's meetings schedule. Must be comfortable taking care of a baby and a toddler at the same time. We love working with education and nursing students as we usually only need 10-20 hours/week and the hours can often be flexible around the student/class schedule. Must be CPR certified. Looking for someone who is an expert in early childhood education and great with the toddler stage as well as infant age.
