Halloween is a great time to share the United States culture with your au pair. Even preschoolers can paint a pumpkin (use washable tempera paint and clean up quickly) and older kids can carve pumpkins with guidance. Costumes provide lots of topics or conversation. And of course Trick-or-Treating is fun for everyone! Talk to your au pair about similar customs in her home country. She may have some great ideas – Mexican au pairs can share traditions around the Dia de los Muertos, for example.
