    ### Response:
    Cleft lip and cleft palate are birth defects that occur when a baby's lip or mouth do not form properly. They happen early during pregnancy. A baby can have a cleft lip, a cleft palate, or both.    A cleft lip happens if the tissue that makes up the lip does not join completely before birth.
