What age santa Claus stop coming to a child's house?

Opinions:-I say it is nine years old.

-I was in third grade and 8 years old. But I have a friend who still believed in fifth grade, when she was 10. I'd say usually 7-9 years old but it varies.

-The age varies depending on what the kids at school think, what they read online, and what their parents tell them. The AVERAGE range is 8-10. Some kids stop believing at a younger age, and some at an older age.
