By Mayo Clinic staffA cleft lip and cleft palate usually are apparent at birth, and your doctor may start coordinating treatment at that time.
A submucous cleft palate, which is "hidden" by the mouth's lining, may not be diagnosed until later when signs develop. Some babies with this type of cleft have trouble with feeding, including nasal regurgitation and excessive gassiness. Later, as speech develops, you may notice a nasal-sounding voice or increased nasal discharge. If your child has these signs, see your doctor.
