If one child has a congenital anomaly will our future children have them too?

Consultation needed. Some anomalies are sporadic,like toe amputations from amniotic bands, while others like cleft lip/palate have a recurrence risk.Most children's hospitals or medical schools have a medical geneticist on staff who can help. A review of the anomaly and both family histories can help define your risks of a repeat, or any other learking issue.
Can have problems. The chance on next child with a problem depends on the type of anomaly. Consultation with a geneticist may answer your concerns.
