We have a houseful of cousins right now, and the kids are in heaven. The adults are doing a lot of crowd management, but we are getting into a rhythm that makes the days doable. For instance, yesterday, we got everyone to the Franklin Institute in the morning. We came home for lunch (and my toddler fell asleep in the car as usual). We fed the kids, then I went for a run (it was almost warm!) Then I played outside with the little kids some while the big kids and Daddies went to Star Wars. When my toddler niece got up from her nap, the younger kid contingent went to the Please Touch Museum for an hour before it closed. Then everyone met up at home for dinners (pasta for the kids, and later on my mother-in-law's seafood casserole for the grown ups). The day before had been the zoo in the morning, a run during nap, then cousins arriving and presents, then playing outside for the last 30 minutes of daylight. Pizza for the kids and tenderloin after toddler bedtime for the adults.
One thing that occupied much time on Christmas day: my daughter received the Frozen castle for Christmas. It was one of those KidKraft flat packs, and I had kind of assumed my husband planned to assemble it, but when I got home from church later on Christmas morning (no one wanted to go with me) he handed me the Phillips screwdriver. So I followed all zillion steps and built this three story masterpiece. I think it came out pretty well.
Hope everyone is having a happy holiday!
