When Nothing Works
If none of the 5 reasons seem to apply to you, consider taking a different approach. Have a heart-to-heart conversation with your kids and be sure to leave judgement and blame out of it. The parent-child relatonship is always a complicated one. Simplify your expectations. You'll find you get more when you expect less. Be a good parent and give the kids a break. If all else fails, fall back on your sense of humor.
