Patient's question:
Four months of poor leg support, unable to roll over, can laugh out loud, can cry, can follow objects and sounds, can communicate with adultsDoctor's answer:
Hello, normal children turn over actively at 3-4 months, start crawling using their upper limbs to support their bodies at 5 months, can arch their backs and sit independently at 6 months, sit steadily at 7 months, crawl on their stomach at 8 months, and can stand with support between 7-9 months. By 12 months, they can walk independently without support. If a child's motor development is significantly delayed compared to normal children, it should be a cause for concern. Generally, the first 6 months are the key time to detect infantile cerebral palsy. If you feel your child is not normal, but do not jump to conclusions too early. Pay close attention to their development regularly, and seek medical attention promptly to avoid delaying the condition, which is the most important thing.
