Shane and I have observed that Sierra is making better sounds, more interesting sounds. While in Prague the doctor WITHOUT hearing what results we were seeing from the Stem Cell said that the next things for us to focus more on is getting Sierra to grab things. He said when a child starts grabbing they also start saying some words. He said this is a level of development that a child reaches. The two go together. It's amazing because I could not work out why I was only seeing results in Sierra's hands and tongue/ mouth, it seemed so unrelated.
