We met with three women form Fairfax County's Early Childhood Intervention program a few days ago. They came to our house and observed Evan and took a lot of notes. He apparently qualifies for their program, which for him, will include PT with a therapist that will come to our house!
They did an overall assessment of him too and he's basically 1-6 months ahead of his age in every area except Gross Motor Skills where he is about 6 months behind. This makes complete sense because of the balance and tone issues he has on the left side.
