Is it possible to develop lactose intolerance when a child is 6?

Yes: Most of the world's population develop low intestinal lactase levels beginning around age 5. This is most frequently found in those of Asian or african descent. Caucasians, especially those from northern europe, tend to maintain elevated lactase levels into adulthood.
