My first GC was born with an horrendous cleft lip and palate.
It really was a bad one.
She had the lip repair at 3 months and the palate at 8 months, she then had bone taken from her hip and grafted into her upper jaw and today at 21 she is fortunate that her speech and hearing are perfect.
She has had some cosmetic ops on her lip but on the whole the outcome has been good.
My dentist told me he has patients who he would never have know had cleft palates until he saw the tiny signs when looking closely into their mouths.
Try to reassure her.
Last weekend, in Rutland, the first statue in Britain of the late Elizabeth II was unveiled.
