Part-time Summer Nanny/babysitter For 20-month-old (12-15 Hrs/wk) In Concord

We're looking for a caring, nurturing part-time babysitter/nanny for the summer for our child, who will be a year and 8 months old in June. We're somewhat flexible with the times of day and days of the week, but are thinking three days/week, 4-5 hours/day in the mornings is ideal. Daily routine can involve play at home, walking outings, diaper changes, lunch, and possible nap support depending on the timing. We have a back yard for play, are walking distance to the public library, and walking distance to a local park/playground. We are looking for someone with experience with toddlers, who is a clear communicator, nurturing, gentle, playful, and kind.
