How do they do this?

As my time grows near for me to go to D.C. for a conference I wonder how in the world am I going to leave my babies?? I have been extremely lucky to be a stay at home momma and beside the occassional sleep over the kids are usually home with me. I am only going to be gone for 4 days but man it seem like a long time. How does Wayne do it for a year??? As my heart hurts I try to be strong and think to myself this will be so good for the kids to spend 4 whole days with DAD! WOAH! Alright so chin up and drive on little soldier girl, your country (well the family members) need you.
