Yes, knowing that you've helped to improve the circumstances for the children must be a good feeling. I gather their mother is the only family member with a drug problem.
Yes, she is. Actually, the grandparents were granted custody of the children at one time, but they refused to comply with the court order not to return them to their mother and they would give them back to her whenever she wanted them, not really seeing, or refusing to see, why that was a problem. The grandparents are good people and they love the boys, but they have been enablers of the mother and enablers of her behavior.
