What do doctors say when they tell a family the baby has anencephaly>?

Hopefully,the truth. The difficulty of transmitting this info to the parents is much less than the sadness & loss the parents will feel when they get the info. Pregnancy is one of life's gambles & up to 4% have an unexpected event after delivery.Accurate information on how/why/recurrence risks are all part of the problem management. Either the OB or a geneticist /counselor should fill in the blanks.
