Not Meeting Milestones: Refusing to Walk Down Stairs

Video Summary

One of the possible warning signs for autism is not meeting developmental milestones, such as walking up and down stairs. Christian K, who is 2 years, 9 months old, will not walk down the stairs in his house, even with his mother's help. This avoidance demonstrates both Christian's delayed physical abilities and his lack of mastery motivation; that is, his desire to learn skills, become more independent and gain praise from his mother.
