When the kids are with me, I refer to W's house as "Mom's house, and I use "our house" when referring to where they are now, and call it home. W recently took the kids to Disneyworld for five days, and then due to scheduling arrangements, she had them for a couple days after they got back. My son had a baseball game, and after the game he asked his Mom if he could sleep at Dad's. She said ok. I drove us home, and when he went in the door he stopped and took a deep breath in, then out. Then he said "It's so great to be home." I was happy he felt that way about my house, but I was sad that he feels he has to spend so much time away from his "home".
