In the prone developmental posture, which activity is recommended to promote weight shifting and extensor strength?

• A. Carry in prone
• B. Sit upright in chair
• C. Stand with a stander immediately
• D. Pull to stand from prone

Answer: (A)

Weight shifting and trunk extensor strength in the prone posture come from activities that keep the infant in or initiating from prone and allow controlled weight bearing through the chest and arms. Carrying in prone places the baby face-down and enables the caregiver to gently shift weight from side to side and a bit forward, prompting the neck and back extensors to engage to lift the head, align the spine, and stabilize the upper body. This builds shoulder girdle stability and trunk control, which are key for progressing in prone. Sitting upright in a chair changes the context entirely and does not develop the same prone-extensor work. Standing with a stander immediately emphasizes upright loading through the legs rather than strengthening the prone back and neck muscles. Pulling to stand from prone focuses on transitioning to standing, which shifts emphasis away from developing sustained prone extensor strength and weight shifting.
