Hi both my son,14 and my daughter,9, have ADHD, and oppositional defiant disorder. They were born addicted to Heroin, meth and alcohol. My sister did not care what she did or take while carrying the kids. I have worked,at times fought, with mental health organizations here in Colorado and now my 14 year old is on the deans list at school and no longer takes any drugs. My 9-year-old had a greater addiction and has had a tough 3 years but has come from be aggressive, screaming child to a loving caring child who just came back from a week long camp with the boys & Girls club. 2 years ago this would not be the case. It has been tough especially like you being a single parent and each child is different but I would be glad to talk in detail if you would like. Please let me know. Don
