When it comes to writing a holiday shopping list, Miranda Kerr is a pro. But with gift-giving season rapidly approaching, the Australian model is on time crunch—and she’s starting to feel the pressure. “It’s all coming up too fast,” Kerr told InStyle last week in New York City, moments before unveiling the Swarovski star that will top the Rockefeller Christmas Tree.

Luckily, Kerr’s mission to find the perfect presents begins months in advance. “I just write down a list of everyone I need to buy for—which is quite a lot,” she said. “I make little notes throughout the year about what each person has mentioned, and I make sure they haven’t gotten it for themselves yet by the holidays.” Ultimately, her goal is simple. “I like to get meaningful presents that people are not necessarily expecting, or something that they’re really hoping for,” said Kerr.

When it comes to her friends and family, Kerr easily picks up on clues about what they want. But there’s one person in her life whose mind is a bit trickier to read: her 4-year-old son Flynn. “I’ve said to him, ‘Ok, let’s write a Christmas list for Santa,’” said Kerr. “That way, I feel like I can get a gauge on what it is that he’s hoping for—not that he’ll get all of it, though.”

The two sit down and come up with an all-encompassing list. “He’ll tell me what he wants and I’ll say, ‘Okay, I’m going to post this to Santa now,'” said Kerr. Even once they’ve written Flynn’s wish list, Kerr explains to her son that he may just end up getting something else entirely. “I tell him, ‘Maybe Santa has something else in mind for you that you might really like.’”

In the end, Kerr leaves things up to the man in the big red suit—or so her son believes. “I tell him that it’s up to Santa to decide, so let’s just see what he brings,” she said. No matter who drops off his presents, we have a feeling that Finn won’t be disappointed.
