Doctor's answer:
Generally, at 3 months, an infant can hold their head up straight, turn their head 180 degrees with their gaze, support their upper body with their arms while lying prone, and lift their head. When lying supine, they can also lift their head. As the head-raising movement appears, around 3 months after birth, the initially straight spine develops its first physiological curve—the cervical lordosis. To ensure normal spinal development, you should not let the child sit up but can help them practice rolling over and lifting their head.At 6 months, when you use a pillow to surround the baby, they can support the pillow with their hands, lean forward, and try to sit upright without falling. This is the time to practice sitting.
