A 10 year old is at a fun age where they're still a kid, but they're also becoming more independent and adventurous. For Christmas, you could get them something that reflects their growing interests and personality. Some ideas include: a cool new toy or gadget, a book or series that they're interested in, a sports equipment or accessory, or a fun activity like a museum membership or a day at an amusement park. Whatever you decide, make sure it's something they'll really enjoy and remember!
