Before the birthday, holiday, or gift-giving event, talk to your child about what is expected regarding personalized thank-yous. If note writing becomes part of family culture, it will be more difficult to rebel against.
Make sure your child sees you sending your own thank-you notes, whether by mail or electronically. Have her help you write them, and make a deal to help with hers.
Involve your child by inviting her to organize the address book or school list, which will make the note-writing part of the process less stressful.
Stock up on kid-friendly cards, as well as other fun materials (stamps, stickers, and the like), before the event.
Incorporate thank-you note preparation into your next art project. A rainy-day craft could be to make homemade cards that can be used throughout the year.
