Question
When a five-month-old baby kicks its legs forward while being picked up to urinate, a sound is produced. The inquiry is about the cause of this sound and whether it is appropriate to have an X-ray examination.
Answer
At five months old, a child’s motor development should allow them to stand with support under the armpits. The sound produced may be due to muscle movement and is considered a normal phenomenon. For such a young baby, unless there are other abnormal symptoms, it is not recommended to undergo an X-ray examination as radiation exposure may affect the baby’s health. Parents can observe whether the baby’s motor development is proceeding in the normal sequence and maintain good communication and consultation with the doctor.
