It first struck me that you loved her even with her addiction and that speaks volumes. That you did not write her off because of her abuse of drugs must have affected her in the most positive way. You also mentioned that because you did not smoke she started to smoke less and then the baby was the final catalyst. It's the kind of great story you want to share with your kids. Your story demonstrates that in the right environment people can change. It doesn't always call for major intervention. I believe you intervened by being patient, and understanding and by just being there. I hope you all continue to thrive.
