It's easy to lose your patience with children, especially when you have 4 of them! Getting the kids out of the house on a daily basis helps tremendously. Weather it be a park, the mall, a pool, or just a walk around your neighborhood or street. It seems that too much time in the house gets kids bored and then they tend to wear on your nerves. At least that's the case with my kids. Also, when I feel myself losing patience and feeling at the end of my rope I immediately stop what I am doing, close my eyes, take a deep breath, and think about what my life would be like if I lost them. It will make you appreciate all of the whining, begging, why's, and so on. You have to also take time away so that you miss them and appreciate them more. Try to take 1 night a week and go out. Go shopping, out to dinner with a friend, or even a simple pedicure can help. Anything away from home diverting your attention from the kids. Hope that helps, good luck!
