Question
A four-month-old baby can’t lift their head and has no strength in their legs. Everything seems normal. What could be the situation?
Answer
Based on your description, the four-month-old baby is still unable to lift their head and lacks strength in their legs and feet. First, consider whether the infant has muscle stiffness caused by hypoxic brain injury. Another possibility is a calcium deficiency. It is recommended to take the child to a pediatric neurology department for examination to check for brain damage. If the child has no brain issues, it may be due to a calcium deficiency. You can supplement the child’s calcium, observe for a period of time, and pay attention to vertical head movements for the child.
