Babysitter Needed for my Children - Full-time / Part-time

Looking for someone with experience taking care of a newborn/infants. Our son will be 5 months old when the job starts. I will be working from home, but will need someone taking care of him while I work. We have a bulldog and a cat, so they need to love animals and be comfortable around them. We live in a row house and have lots of stairs. I work on the third floor, where his nursery is also located. Hours are slightly flexible, as well as days of the week if certain days/times are preferred.
