Before the palate is repaired, there is no separation between the nasal cavity (nose) and the mouth. This means that the child cannot build up air pressure in the mouth because the air escapes out of the nose. The roof of the mouth has very less tissue for the tongue to touch. These problems can make it difficult for the child to talk. Once the palate has been repaired, your child may be able to learn more words and speech can be improved with training and encouragement.
