My sister had twins and one had a clubfoot on the left. Her mother-in-law is saying it’s because the babies were too crowded and the other twin caused it by taking up too much space. Is this true?

Doctors don’t know what causes idiopathic clubfoot, the type of clubfoot that a baby may be born with. The clubfoot presents with the foot pointing down and inwards and the baby is not able to straighten the foot to put it in the normal position.

Some children are born with their foot or feet pointing downward that may look like a clubfoot, but after x-rays and examinations, it is just the foot is in that position because of the baby’s position in the uterus. This does not need the same type of treatment as a true clubfoot. If your sister’s baby has a true clubfoot, it’s highly doubtful that it occurred because of crowding in the uterus.
