Hi Brandi, we have not heard of any cases like that. We actually brought your question to Dr. Atila, the physician in this video, and he said if it happens/happened "Either this is pure coincidence, or I could imagine the following: The mother could have a very mild congenital/hereditary form of DI/AVP-D. Pregnancy could then lead to an increased degradation of vasopressin by the placenta, and symptoms would then appear for the first time during pregnancy and “resolve” after pregnancy. We sometimes see this in very mild forms" He added that he would suggest a genetic test to the mother. Hope that helps answer your question!
