My sister "A" and I shared a room growing up. We had bunkbeds, me on the top bunk and A underneath. I don't remember if it happened that way because she wanted the bottom and I wanted the top, or if I demanded that I got to pick first because I was older...but I suppose that doesn't matter now. What does matter is how much fun we had at times! We made up a bedtime game, "Bird & Worm". One of us would lean over the edge of our bunk, wiggle our finger around like a worm and wait for the other one to try and catch it. Whoever was the "bird" could only use one hand to catch the other's finger, and if the "worm" could pull out of the bird-hand it didn't count. We had so many fun nights, staying awake late when we were supposed to be sleeping, trying not to make too much noise giggling. What fun to share a room with my sister! (Of course, you never would have heard those words when we were in the thick of growing up!)
E has just started her own version of our bedtime game. When we're lying all snuggly in bed, she starts waving her hand as if to say goodbye. She waits for me to grab at it and giggles like crazy when I catch her! Sometimes she pulls away real quick and sometimes she lets me catch her hand in mine. When I do I squeeze it a little and tickle her palm, which makes her laugh even harder! It usually only takes a few rounds of this for her to settle down and nurse to sleep. Obviously content knowing she taught her mama a game.
