No humidity for mine either, and we live in AZ. Mine had a lot of stuck shed and dimples in his eyecaps, I soaked for the shed and the caps returned to normal - he just needed to get some water. Good luck with her, I think mine is small for his age as well, hes about 3 and my 07 is almost as big as him.
