Part-Time Nanny For Active 21 Month Old Boy

Looking for an energetic, creative caregiver to help with our toddler son during the late pregnancy/postpartum period. We're expecting our 2nd son in mid-March, & would love for our firstborn (21 mo in February) to still feel extra special & be able to attend his regular activities (park, open gym, music, gymnastics). Caregiver must be comfortable w/ large dogs (friendly, 80 lb Airedale) & attending classes/hanging out with mom or grandma too! Though most classes are walking distance, we'd like them to be comfortable driving in case they want to go to nearby museums. While we're thinking M/W/F through late May, the schedule can be negotiable for the right fit. :) Our son is allergy-free & an extremely happy little guy. He LOVES basketball & other physical activity. He's starting to engage in imaginative play & is a lot of fun!
