Last week the ten-year-old started asked to call my parents. He called them 6 times in 7 days.
I commented to my wife that this surprised me. She then related to me a conversation they had had with his psychologist. The psychologist had been asking him about times when he had been feeling bad and then started to feel better. One of the things that he came up with was that talking to Grandma and Grandpa on the phone had cheered him up the previous week.
Apparently he has seized on that idea as a well to feel better in general. He is also starting to branch out to other family members. He called my aunt and my brother over the weekend.
It is very exciting for us to see him starting to build a social support network.
