Mason's New Accomplishments

I just went to get Mason up from his nap and found him sitting up!  That is a huge step for him!  He has never been able to get to a sitting up position from laying down before.  In the past couple of weeks he has started getting up on his hands and knees from his stomach.  He has also been able to get to a sitting up position when I put him down on his hands and knees.  But he hasn't been able to go from his stomach to knees to sitting...until today!  Yeah!
