This Melissa and Doug Wooden Advent Calendar is both fun and interesting for kids. It features a wooden tree with 24 magnetic ornaments and a gold star tree topper.
This is a great option for toddlers (and for parents that want to teach about numbers). The wooden Christmas tree allows the kids to hang an ornament for every day of the advent, getting a nice visual reminder of how many days Christmas is away. For parents that want to skip the treats, and have a calendar that can be used year after year, this wooden toy advent calendar is a great option. You can buy the Melissa and Doug Advent Calendar at Chapters Indigo.
