Babysitter wanted (san mateo)

Hi -- we are looking for an experienced babysitter for Wednesdays 10-2 and Saturdays 9-1.
We can be flexible but one weekend day and one weekday is a must.
We have two girls: one is 15 months and one is 2 years, 9 months.
Both are in diapers.
We're looking for someone to walk them to playgrounds, feed snacks, play with them, read books, etc.
They are both smart, fun, and healthy.
We're looking forward to meeting you!
