Nanny Needed For 2 Small Children

We are a family w/ 2 little ones in an apartment. We are looking for a nanny to watch both of our boys (one is 5 months old and the other 3 years old) paying $20 per hour. There are parks within walking distance from our place. I work half the day or more in my living room so that I can be near my boys while a nanny looks after them. It's a great position since most days I should be able to help with putting the boys down for their naps, taking them to the park, and nursing the little one. Light housekeeping would be helpful. We would prefer a nanny who has their own car and who does not smoke. We have some flexibility in our scheduling so please let me know if you are interested in any of the below shifts. Mon, Tue, Wed 8am-5 p.m. or Mon, Tue, Wed 12:30pm-5 p.m. or Mon, Tue, Wed, Thu 12:30pm-6:30pm
