Nanny Needed For My Children

I am looking for a part-time nanny for my son who will be 4 months in July. The position would be 3 days a week with the days varying each week due to my work schedule. No weekdays or holidays. 9am- 5 p.m. No housework other than prepping and cleaning bottles for feeds. Must be ok with a parent working in the home. Would love someone to take him on walks and interact with age appropriate play.
