Did something I did or did not do during my pregnancy contribute to the cause of Cleft Lip/Cleft Palate in baby?

Expectant mothers who do not take prenatal vitamins and do not receive prenatal care are associated with a higher increase in complications in the newborn period as well as structural deformities at birth (congenital anomalies). However, because cleft lip/cleft palate is such a complex anomaly, it is very difficult to pinpoint the cause or directly relate causation to something the mother did or did not do.
