Toddlers and tree trimming, while cute, are a dangerous mix.*
Please be advised: Do not purchase a new star if you have an aspergian in your family. If you do, make certain he sees the new one lit and changing rainbow colors on the top of the tree before he gets his hands on the old star. This manuveur will save you a lot of loud grief.
The cynical teen may appear from his hovel bearing the greeting, (deeply inhaled squeal intro) "How dare you start decorating without me!"
*No toddlers were harmed in the making of this post. A christmas ball, however, is doomed.
Uberflea update: they are still in residence, though food grade diatomaceous earth has been purchased. Tree trimming took precedence.
