It's important to keep your baby away from the Christmas tree for their safety. To prevent them from getting close, you can use a baby gate or fence to block off the area around the tree. You can also hang ornaments higher up on the tree, out of the baby's reach, and make sure that any breakable ornaments are out of reach as well. If your baby is curious about the tree, you can distract them with toys or other activities to keep them occupied.
