Twin Mom
We have identical twin boys, age 7. One displays symptoms of SPD and the other does not. Is this a genetic disorder? We are evaluating him for ADHD as well. His incessant chewing on non-edible objects, among other behaviors, has had us baffled for years. Surprisingly, he does very well academically in school. We just can't get him to keep things out of his mouth and stay in his chair!
