From the University of Iowa Hospitals:
Pigeon toes, or in-toeing, is a condition causing the toes to point inwards. It is common in infants and young children. If a child is pigeon toed it does not mean there is something wrong with the feet.
Most children outgrow pigeon-toes and do not need treatment. In some cases it may take several years before the pigeon-toed foot is straight.
My suggestion: Don’t worry about it.
