When a child has an anxious thought, they are usually convinced that this thought is true, and that the danger is real. To remind them that this is not necessarily the case, or to help them deal with their thought, work together to find a sentence that they can repeat to themself when experiencing anxiety. They can write it down or cut it out to have with them as a reminder.
Mandalas are an excellent way of concentrating on things other than your thoughts.
