Reliable daytime babysitter needed for infant

Hello! We’re looking for a babysitter for our 7-month-old son. I work occasional weekdays, and/or need childcare on days when I have appointments with my other children. I am looking for either a scheduled 1 day per week and/or flexibility with other days. We have a goldendoodle at our home. He is very friendly. He is trained on the invisible fence and would just need to be let out on occasion depending on how long the babysitting day is. We also have a 3 and 5 year-old. They are in school full-time, but may be home on occasions, and/or need to be met at the bus in front of the house.
