Well, we found out at therapy that Allie's hamstrings are tight and we need to help her to stretch them so that she can place her heel fully onto the ground.  Also problematic is the fact that her tone has tightened in her arm, wrist and hand and her grasp is almost non-existent.  Rough day when you realize that your baby girl is going backwards.  I knew she was having TiAs every day, but am praying that this is not what is causing all of these troubles.
