This week, KJ visited an orthodontist and he confirmed what our dentist said "KJ may be developing a cross bite", but that he couldn't be sure until she was 7 years old.
Fortunately 7 is still young enough to correct the problem without major brace action. Unfortunately, KJ is still 2.5 years from being 7, and at that time we will most certainly be on our journey. Val explained this to the orthodontist, and he mentioned something interesting. He said that "Brazil and Argentina are excellent places to take care of this. They have excellent dentists and are very cheap."
Val shared with me that the orthodontist's wall was covered with mementos of the his journeys around the world. He was a kindred spirit and encouraged us to go!
