First thing, re-group, if you can get a relative (or trusted friend) to Babysit, take 1 whole day, go to the spa and have a relaxing full body everything. Second, I found that when I was at the end of my rope, I realized in order for my children to change behaviors, I had to change mine...Third, try not to focus on everything the children do wrong, that only encourages that behavior. Focus on any little thing that they each do right. Encourage team work, for example: challenge the 2 older children to clean their toys up, while challenging the 2 smaller ones to see who cleans up the "nicest"and reward them with a story, or family game, treat, etc. Try audio books, what I am trying to say is redirect all of their behaviors, encourage them while praising them, and make sure they each know how proud of them you are. POSITIVE reinforcement will always work. I am not an expert, I do know change comes from within...I wish you luck, I know things aren't easy, but they will get easier if you try...If you feel like you're at the end of your rope, tie a knot and hang on...
