What developmental milestone is the best predictor of functional outcomes for children with CP?

Sitting independently by 24 months is often regarded as a critical developmental milestone for children with cerebral palsy (CP) because it is a foundational skill that influences a child's ability to engage in further motor activities and social interactions. Achieving independent sitting demonstrates core strength, balance, and postural control, which are essential for subsequent development in mobility, self-care, and exploration of the environment. Children who can sit independently are more likely to develop other skills like crawling or walking later on, and this milestone can be indicative of overall functional potential as they grow.

In children with CP, the ability to sit independently often correlates with better outcomes regarding mobility and independence later in life. This skill suggests that the child has made substantial progress in motor development, which can open pathways for further skill acquisition, including walking and running, and may enhance their participation in daily activities. Thus, sitting independently serves as a strong predictor of the functional outcomes in these children.
