Four. Well, this one is still evolving, but since we have very young children that still try to destroy the breakable ornaments, we have been trying out the idea of an “interactive tree.” The children love to decorate the tree, so we went with that motivation and decided to keep a craft box with a few simple supplies to make Christmas decorations available. The children make them, put them on the tree themselves, and move them around as they please. It’s worked well except last year a prolific 3-year-old scribbled out 20 pages of notebook paper and pigeon-holed them all over the tree so that it looked more like a papier-mâché mess than a symbol of eternal life, but, oh well. The star was still at the top and one big ornament that says, “Believe,” was still visible. I like the idea of the interactive tree and homemade decorations though. This could mature as our family matures.
