LEGO Kids love Christmas for obvious reasons, and advent calendars are an easy way to keep up the Christmas spirit in the days leading up to December 25. There are advent calendars for every age and every interest, so we've rounded up a wide variety of calendars to delight your toddler, older kid, or teen. The cheapest kids' advent calendar in this list is only $6.99, so you can delight your child for less than $0.30 a day. I absolutely love Christmas time.
