嬰兒發展里程碑（Developmental milestones）是兒科護理評估的關鍵。6 個月大的嬰兒，其神經肌肉系統已發展到足以支撐軀幹，能不需協助維持坐姿（Sitting without support）。這是評估嬰兒大動作發展（Gross motor development）的重要指標，若無法達成，需進一步評估神經發育狀況。
Sitting without support is a typical gross motor milestone for a 6-month-old infant, indicating adequate trunk control. Other listed skills, such as walking or running, develop much later in childhood.
