Good idea. It can work on children at a young age, but trust me Elise, once the kids get past 12 or 13, they don't think like that. They only care about what they want.
I raised my boy for the last 5 years as a single Dad, so I know where your coming from. We used to have a retreat password too, but it does not solve the issues.
Now I have a house full of teenagers. Margaret s two daughters 18 and 17, my boy 14, and her boy 12 and they don't let up.
However, if it works for you now, then that is great. It will help you to get further along into managing your symptoms.
