Babysitter

Looking for a babysitter for our 17-month-old daughter, several Fridays per month (typically 2nd and 4th Fridays). Hours are flexible but generally would be 7:15 a.m. or so until maybe 12-2 p.m. Again, flexible depending on mom's work schedule and what is going on. We do have a 2. 5-year-old golden retriever dog, very mild mannered but sheds and would want the person to be ok with dogs. Non-smoker please. Experience with babies and toddlers (who are not toilet trained and need diaper changes) is preferred.
