Flexible babysitter/nanny needed for infant, comfortable with pets.

Hi, My wife and I are looking for a nanny/sitter to watch our three month old between 9 AM and 5 PM during the weekdays. I work from home and we need someone to sit only during the days when I'll be really booked on my calendar, so this won't be a regular five-days a week gig. Our home has an Australian Shepherd (50 lbs), so you must be comfortable around pets. You will play, feed, and change the baby, ensuring a safe environment. You will help with nap times. We're looking for someone reliable who can build a positive connection with our little one.
