A letter to Santa is one of the oldest Christmas traditions, and it is one a child can do almost on their own. A little help with the wording goes a long way, and a short, clear letter is far easier for grown-ups to act on than a list of forty things.
Start with a greeting and a thank you
Most children begin with "Dear Santa" and then tell him how they have been this year. A thank you for something specific, such as a day at the beach or a new pet, makes the letter feel personal and gives you something to mention in the call or email if you book one.
Keep the wish list to three
Ask your child to choose three things they would most like, then one that is a surprise they could hope for. Three is enough to be generous and short enough to read. If they cannot choose, let them list everything and then go through it together, crossing off the ones that are too big or too expensive.
Add a drawing
A drawing is often the best part of the letter. It can show a reindeer, the sleigh, or a picture of the family. Parents often keep these for years.
Post it, or send it to a grown-up
Some families post the letter, some leave it on the windowsill, and some put it in the fire on Christmas Eve, which children love to watch. Whatever you choose, make the ritual part of the fun.
Reply in return
A short reply from Santa, written by a grown-up in a looping hand, is a delight. Mention one thing from the letter, say thank you for the drawing, and remind them that elves are checking the list.
