A more common cause of intoeing in infants is secondary to a turning inward of the front part of the foot. This is called metatarsus adductus and is caused by the way your baby was positioned before he was born. Although it turns inward, the foot can be easily be moved to a normal position. This condition corrects itself as your child gets older.
Another cause of intoeing is due to the shin bone or tibia turning inward. Tibial torsion is usually noticed once your child is walking and will also correct itself without treatment. A third cause of intoeing is medial femoral torsion, in which the thigh bone or femur turns inward. This condition is more common in older children and may get better quicker if your child sits with his legs crossed in front of him, instead of in a W style.
