In teaching your children the importance of gratitude, writing personal notes to friends and family is a great hands-on activity to put the lesson into action. After the next holiday or birthday in your house, skip the preprinted or fill-in-the-blank notes and instead invest in a special set of stationery. If he is too young to write, let him dictate what he'd like his message to say. And even if he's just getting started with a pen and paper, thank you notes are a great way to practice. Here are some of our favorite options for kids stationery that's uniquely their own!
