Babysitter - Full-time / Part-time

We are looking for a great nanny for 2 children. I need assistance with one of my children at a time, thats what would be most of the time and in extraordinary cases the two of them. My boy is 21 months and my youngest 5 weeks old. We reside in Mount Prospect and we would prefer someone who could help out with light housekeeping. Someone with their own car and CPR is preferable as the oldest has multiple food allergies.
