Sentimental and practical: Christmas trees require a lot of ornaments, so start your child's collection now. Each year, gift your kiddo with a decoration that speaks to what they're into that year. A reindeer playing hoops, perhaps? Or a photo ornament featuring Oscar the family bulldog? By the time she's ready to fly the coop, she'll have plenty to fill her own tree. If you celebrate Hanukkah, why not create a new dreidel annually? You can buy kits online.
