Regarding the kids. Prayer helps a lot. "Courting" them and loving them for who they are helps, too.
Here's somethign that helps me: when I yell, blow my stack, or go over the line, I ask for their forgiveness. I tell them I over-reacted and apologize. Try that -- it's sexy, too.
Or when they interrupt...try a hug and a kiss and shoo away.
Reading fun stories to them is cool too. I'm reading my 7 year old the Hobbit, by Tolkien.
