Grandfather Adams came up this weekend to play with Shattuck.  He learned a lot from this visit.  Grandfather would record Shattuck yelling in his I-Phone and play it back to him.  Shattuck would respond to his own voice in kind (definitely a form of communication).  He wanted to touch the I-Phone so we put him on the floor.  He belly crawled to the phone.  Then he continued on to the window and tried to pull himself up.  Everyweek is something new.
