British Expats Looking For Chicago Nanny (Part Time From August, Then Full Time From December)

We are looking for a great nanny for our first child. We are British expats - we have a comfortable single family home with yard, nursery & one very friendly dog called Rufio! The requirement is for someone who can join us full time when my wife goes back to work in December (Mon-Fri ; 8am-6pm). We would prefer a nanny whose first language is English, does not smoke, who is comfortable with a friendly dog and who is CPR certified.
