Babysitter Needed for my Children - Full-time / Part-time

We are looking for a great mother's helper nanny for a 3. 5-year-old and baby in Elmhurst. We would prefer someone who could help out with light housekeeping and help both girls at various times. Sometimes baby would be with me ( exclusively nursing) and toddler would need activities in afternoon. Other times may run out for errands one morning a week and leave baby for naps etc. We would prefer a nanny who has their own car, who does not smoke and who is CPR certified.
