Nanny Needed - Now Hiring

I am in need of a babysitter for the evening of Saturday, 9/19 for my 21-month-old son. He will be finishing dinner and beginning bedtime around the start of the babysitting time, so most of the time will just be monitoring the baby monitor. My wife and I will be at a concert with no cell phone access, so the babysitter should need to feel comfortable without being able to contact us for a 2-3 hour stretch. Our son is a very good sleeper and once he is asleep, he almost never wakes up or has any problems. So the evening should not be too difficult! We also have two cats who are very friendly who will need to be fed a can of food but are otherwise very low maintenance.
