Babysitter Needed for my Children

I'm looking for a great recurring sitter for our 3-year-old. Specifically hoping for someone to come in every second weekend for the morning on either Saturday or Sunday until he goes down for his nap (7. 15 - 1. 15). Would also be interested in the occasional weekend evening. We have a newborn at home too that we will be looking after. Just hoping to get someone caring to help entertain our toddler / take him out to the park etc. We would need someone who is comfortable around pets, since we have a beagle named Milo (who is very chill and friendly).
