A Christmas letter in two languages, with one shared plan.

Agree on your family’s names

Ask which names your family uses: Santa, Baby Jesus or another familiar name. Explain that different relatives have different traditions. You do not need to rank them or make one relative give up their own language.

Write in a language your child understands

For a paper letter, write in the language your child understands best. You can add a greeting in the other language and explain it as you read. If you prefer two versions, make sure both say the same thing about when the surprise comes and where you will be.

Keep the same story in both languages

Use the names your family already shares. A letter can be in English and discussed in Czech, Spanish or another familiar language without changing the visitor or the day’s plan.

Compare the action in both versions: who is speaking, where the invitation leads and whether gifts are today or tomorrow. A natural translation can use different words while keeping that plan unchanged. Send the wording to a grandparent beforehand if they will read it.

Here is a fictional English-and-Czech pair for a family that calls the visitor Baby Jesus: “Dear Mia, after dinner, look beside the tree for my next letter. Baby Jesus.” / “Milá Mio, po večeři se podívej ke stromečku, kde najdeš můj další dopis. Ježíšek.” Both invite the child to the same place after the same meal. Replace the name, place and moment together in both versions; choose your family’s own visitor rather than adding a second one in translation.

Read both versions aloud before sending them. If one says “tomorrow” while the other says “after dinner”, settle which day you mean and correct both; a fluent sentence can still send the child to the wrong moment.
