Learning to walk takes time and practice, and it's common for kids to start walking with their toes and feet turned at an angle. When feet turn inward — a tendency referred to as walking "pigeon-toed" — doctors call it in-toeing. When feet point outward, it's called out-toeing.
It can be upsetting to see your child develop an abnormal gait, but for most toddlers with in-toeing or out-toeing, it's usually nothing to worry about. The conditions do not cause pain and usually improve as kids grow older.
Almost all healthy kids who toe-in or -out as toddlers learn to run, jump, and play sports as they grow up, just the same as kids without gait problems.
In-toeing and Out-toeingMost toddlers toe-in or -out because of a slight rotation, or twist, of the upper or lower leg bones.
Tibial torsion, the most common cause of in-toeing, occurs when the lower leg bone (tibia) tilts inward. If the tibia tilts outward, a child will toe-out. When the thighbone, or femur, is tilted, the tibia will also turn and give the appearance of in-toeing or out-toeing. The medical term for this is femoral anteversion. In-toeing can also be caused by metatarsus adductus, a curvature of the foot that causes toes to point inward.
The reason some kids develop gait abnormalities and others don't is unclear, but many experts think that a family history of in-toeing or out-toeing plays a role. So, if you toed-in or -out as a child, there's a chance that your child could develop the same tendency. Additionally, a cramping of the fetus in the womb during pregnancy could also have led to in-toeing or out-toeing.
As a fetus grows, some of the bones have to rotate slightly to fit into the small space of the womb. In many cases, these bones are still rotated to some degree for the first few years of life. Many times this is most noticeable when a child learns to walk, because if the tibia or femur is tilted at an angle, the feet are, too.
