Babysitter Needed - Full-time / Part-time

We are looking for a great part-time nanny for 1 child in Chicago. We are open to 2-3 days a week, with flexible hours during the workday (around 9 or 10 a.m. to 3 or 4 pm). We have no pets and are looking for a non-smoking nanny that can contact nap with our child, take him on walks, play with him, and keep him safe. For the time being, my husband will be home but mostly busy during the day.
