A twelve-year-old boy is typically at the age where he is starting to develop his own interests and hobbies. It's important to consider what he enjoys and what he might need in order to make an informed decision about what he wants for Christmas. Some general ideas could include: a new gaming system, a bicycle, a camping kit, a new musical instrument, a science kit, a drone, or a new hobby-specific tool (such as a paintbrush set or woodworking tools).
