Childcare Needed

I am seeking a nanny to come 9am-3pm, 2-3 times per week, to look after my 6-month-old baby while we are working. My wife works from home and my mother-in-law lives with us and helps watch the baby while she sleeps, but she is usually awake about 4 hours of that 6 hour window. It would be very helpful to have someone help watch her, play with her, take her for walks around the neighborhood, and feed her.
