Babies may have cleft lips with or without cleft palates. Cleft palates may also occur without cleft lips
Cleft lip is a congenital malformation in which the left and right sides of the upper lip do not join up properly. There may be genetic influences, as well as environmental or nutritional causes, but these are poorly understood. The proximate cause of cleft lip is a fusion defect, though.
Cleft lips and palates occur due to a combination of genetic and environmental factors during early fetal development. These conditions arise when the tissues that form the lip and roof of the mouth do not fully fuse, leading to openings or splits. Factors that may contribute include maternal smoking, certain medications, nutritional deficiencies, and genetic predispositions. However, the exact cause can vary for each individual, and often, the exact reason remains unclear.
Cleft lips may involve one or both sides of the lip
As well as unilateral or bilateral, cleft lips are further classified as complete or incomplete. A complete cleft is the entire lip, and usually the alveolar arch. An incomplete cleft involves only part of the lip.

"Scientists are researching methods to prevent cleft lips and cleft palates. One finding, according to research studies, is that mothers who take multivitamins containing folic acid before conception and during the first two months of pregnancy may reduce their risk of giving birth to a baby with a cleft." - content provided by OperationSmile.org (see link below for more information) As of now, there are no cures for a cleft lip or palate other than surgery after the child has been born.

The length of the opening ranges from a small notch, to a cleft that extends into the base of the nostril
The condition is congenital; that is, babies who have cleft lip, cleft palate, or both are born with the condition. For more information, see: http://familydoctor.org/online/famdocen/home/children/parents/special/birth/034.htmlit is a birth defect
There is no known means of preventing clefting
