Babysitter needed for one 6 month old boy, comfortable with a calm older dog

We want a responsible babysitter for our 6 month old boy. The start date is October 10th, but we can be flexible. You will look after our child in a home with a 25 lb mixed breed older dog. You must be comfortable around dogs, but will not be responsible for his care (he likely will just nap!).
Your main tasks include feeding the baby, changing diapers, and providing safe playtime. We value someone who can communicate well and maintain a safe environment for our child. If you have experience with infants, we would love to hear from you.
