Family of 4, dad is a surgeon and works full time (8a-4:30p on average). Mom is currently a SAHM. Oldest is currently 3, and our youngest is 2 months. Our oldest is currently in 3-days a week preschool (half day from 9a to 12p) and will be increasing to 5 days a week (also half day) next year. We do not plan on having any more kids for the foreseeable future.
Play with the toddler for the most part, and maybe occasionally spell mom from holding the baby on occasion. We would be willing to pay extra to help with light housework such as cleaning the table after meals, loading the dishwasher, and at least switching laundry over (if not actually putting it away).
We currently live in a townhouse community that is very safe. We probably only need help from 8:30 onwards to help get the toddler to preschool (15 min walk from the house, or 3-4 min drive), up until dad gets home around 5p on average. Again, willing to pay more as needed if weekend hours are required.
