Looking for a babysitter for three children, ages infant and elementary

We're looking for a reliable babysitter for our three children, who are in elementary school and an infant. We have a Bernese Mountain Dog who barks initially but is sweet once she warms up. Your responsibilities will include engaging the kids in activities, preparing snacks, and ensuring their safety. We're seeking someone energetic and attentive to their needs. Our baby may be somewhat difficult for some because she refuses a bottle (she is nursing still; we would love it if she took one) and she cosleeps/ nurses to sleep. Ideally a sitter would be ok with rocking/ wearing to sleep and getting her to go down on a floor bed. If this sounds like a good fit, we’d love to hear from you.
