Make the gift about **becoming his to build and use**. He has seen your models on display; taking ownership and discovering how they work can still be a new experience.

For the Lego, I’d suggest:

- **Choose one set that fits his interests and ability.** Giving him your whole collection at once could make it harder for any one set to feel special.
- **Prepare it for a fresh build.** Check the pieces, clean them if needed, and dismantle the model into bags. Include the instructions and put everything in a box you can wrap. Opening a present can still be fun when its contents are second-hand.
- **Tell him briefly why you chose it for him.** For example: “I enjoyed building this, and I thought you’d like the working gears. It’s yours now.”
- **Offer time together.** “Would you like us to start building it this afternoon?” That gives the present an experience to look forward to.
- **Let him decide what happens to it.** Rebuilding, modifying, and combining it with his other Lego are ways of enjoying the gift.

If he particularly enjoys taking things apart, you could give it assembled, with the instructions wrapped alongside it.

Be honest about its history, and keep the story light. “This was mine, and now I want you to have it” is enough; a speech about its sentimental value can make it feel like something he must preserve.

You can make the handover thoughtful, but you can’t guarantee appreciation. Give him room to discover what he likes about it, even if his first reaction is quieter than you hoped.
