Patient's question:
The baby is 6 months old. When held upright, the waist is still very straight and doesn't bend down. The baby arches its back and lies on an adult's shoulder. When held upright, it still won't stand. The legs are always curled and don't stand at all. However, when kicking, it seems strong. When lying on the bed, the feet kick on the bed, and the buttocks can be lifted. Jumping is good, and the grasping ability of the hands is also very good. It can be amusing, chase objects, and make babbling sounds. But the waist is very soft. Even with the legs supporting, it still won't stand. It looks softer than others, and at 5 months, others can already stand with a straight waist. Is there something wrong with our baby? We don't drink much milk; the baby weighs 16 pounds and only drinks 480 milliliters of milk a day. Does that have anything to do with it?Doctor's answer:
Generally, it is considered that the lack of vitamin D, or less holding the baby, or less opportunity to crawl for the baby, leads to weak muscle strength in the baby's waist and back. Let the baby get more sun exposure, use a gradual approach every day to encourage the baby to crawl more, and enhance feeding while providing complementary foods. Some developmental delays, such as premature birth, choking, or breathing difficulties, may require a hospital check-up.
