Nanny Needed For My Children - Full-time / Part-time

We're looking for a warm, experienced French-speaking babysitter for our two children, ages 4 and almost 3. Their dad speaks French with them, and we'd love to add more natural French exposure through an occasional sitter who can speak primarily French with them while playing, reading, eating meals, etc. This is not a formal tutoring position--we're looking for someone who genuinely enjoys engaging with young children and can provide natural French immersion while babysitting. We're looking for occasional/as-needed care rather than a set weekly schedule. Experience with toddlers and preschoolers is important.
