From the the point of view of a husband with a wife who does therapy with children and my own psychology degree and work with others, I had a hard time reading much past the threats and destruction. I think a proper child psychologist is the best course of action at this time. At best its just the child acting out over the situation or poor parenting but It could escalate or be an underlying problem or condition. And if money is an issue alberta does have good funding for children in need of counseling. Thats my point of view not in anyways to be taken as anything other then such.
