 This will be a 3-year longitudinal project recruiting 110-130 children in total. The investigators will have children with CP n6080 and normal n50 from 2-12 years old under consent of their family. The investigators study will be based on structure of ICF-CY. In the first year, basic clinical assessments including motor, mental, vocabulary, motor speech function, general development, and subjective questionnaires on adaptation, participation, development and quality of life will be collected. During the second to the third year, all measurements will be repeated in the end of 6- and 12-month to follow the performance of children with CP and those with normal development.
