Children's belief in Santa Claus naturally changes as they age. Research indicates that about 90% of children believe in Santa until the age of six, start questioning around eight, and by ten, about half have graduated from believing. This transition is not sudden but proceeds through five stages. Initially, children believe in an all-powerful Santa, then move through the "helper theory," and finally, they distinguish between fantasy and reality. This is a natural phase of cognitive development and can be seen as a sign of healthy growth. It is important to embrace this change while nurturing the child's feelings. Especially when siblings are involved, consideration for younger children is necessary. For those who begin to doubt Santa's existence, it is valuable to say, "You can be Santa too," using it as an opportunity to cultivate love and empathy.
