Long Term Nanny For 5 Month Old

We are a fun-loving active family that loves to travel! We are looking for a dependable, consistent, proactive part time nanny for our amazing 5-month-old son. We are looking for someone who can commit to 25 daytime hours per week. We also have a 2-year-old son who will need care occasionally when he is home from preschool. In addition to developmentally appropriate childcare, we would like someone who can do light housework and potentially meal prep.
