Looking for a sitter for my infant with flexible hours on Tuesdays and Thursdays

We're looking for a reliable babysitter for our 5 month old infant starting September 8th. The schedule is flexible, with hours from 11:30 AM to 4:30 PM on Tuesdays and Thursdays. You will be responsible for engaging the child, changing diapers, feeding bottles, putting her down for naps, and ensuring a safe environment. I work from home but occasionally have out of the home obligations, so I may be in and out during your time here. Comfort around our calm and friendly Labrador Retriever is necessary, though you will not need to care for the dog. We need someone who can follow routines and be attentive to our child's needs. Your support will be important to our family.
