As a teacher...let me tell you that to actually get an accurate ADHD diagnosis is pretty hard. His teachers will have to fill out forms, they will test him (they tested my sonfora totally of 4 hours) and they will come back with suggestions.
I took Nick to a center that specializes in pediatrics and one that encouraged non-medication.
I would suggest finding a clinic like that close to you.
(And for mice, use peanut butter on the traps!!!:) )
