Decorate your Christmas tree appropriately for your child’s age. Children who are still "mouthing" items may put ornaments in their mouths.
Put glass bulbs, lights, tinsel and ornaments that are delicate or have removable parts out of reach. Remember that popcorn is a choking hazard for children under age 5. You could place the tree on top of a table (no table cloth) or put a safety fence around it.
