You can learn whether your baby has a cleft lip or cleft palate with prenatal ultrasounds as early as 13 weeks. These birth defects occur when a baby's lip or mouth do not form properly during pregnancy. Together, cleft lip and cleft palate are commonly referred to as orofacial clefts. Though having a baby born with a cleft can leave you feeling distressed, both a cleft lip and cleft palate can be corrected. Most babies can achieve normal function and appearance through a series of surgeries.
