Hello. When young children first learn to walk, they are not yet able to master the correct gait. It is easy to have some seemingly abnormal gaits, such as pigeon-toed, pigeon-toed, stepped feet, etc. When the child runs, he stumbles because of anxiety and in order to maintain balance. Parents should carefully observe if the child has learned to walk for a long time and is still unsteady or may be pigeon-toed. If you need to go to the Orthopedics Department of Children's Hospital, please ask the doctor to check it and rest assured.
