I haven't done it but lots of people here recommend the Parent Effectiveness Training. Apparantly it is really great. I tend to get to the end of my rope (like I did recently in a thread) and then things seem to even themselves out.

What sort of things are you struggling with hun? Are there specific things or is it just that you feel you need help in general? Are your expectations too high for yourself or do you think you are failing your kids in some way? I recommend reading THIS blog in general and that post in particular.
