4 Day In-Home Babysitter Needed For WFH Parents

We are in need of a babysitter for our 9-month-old son while his current sitter (grandma) is on Vacation. My husband and I both work from home but need a little extra help with his care during our busy work week. We are looking for someone who will come to us and handle his needs from approximately 8:30 a.m. til 4 p.m. He takes 2 naps a day and primarily drinks milk, but also has 2-3 puree/mash meals a day. He is not mobile yet so most of the play time spent is floor time or in his activity center. We only ask that the noise level be kept medium-low and TV time to a minimum. We have a 5-year-old, blind Great Pyrenees named Hank who is very gentle and sleeps 90% of the day. We are looking for someone responsible who has experience with young babies. First aid knowledge is important since he is learning to eat.
