Thanks each and every one of you for your kind words and support.
I forgot to mention a couple things:
Spencer has experienced the death of a close family member...almost 2 yrs ago. It happened when he was 3...almost 4. My great aunt was hit by a car while walking her beloved little dashound. She died...but amazingly, Toby, the dog lived and we inherited him. Now, Toby is Spencer's best friend, but he's a reminder of her death on a daily basis, yk? We have many of aunt Jane's things around the house, too.
2 other more distant family member have passed away in that time, as well.
Also, we recently moved to a new state. So his day to day social activities have been brought to a screeching hault and we're homeschooling, so he hasn't met as many new friends.
