Little e suffers from extreme car sickness. We've found that listening to music on headphones really helps her comfort level, and reduces the need for The Bucket. Our errands now have a somewhat comical Name That Tune dimension. Big E and I sit in the front seat and listen Little e belt out (somewhat random) lyric bits and try to guess what the song might be.
For example: Particle Man by They Might Be Giants ala Little e:
"..'an"
"..'an"
"..'an"
"..'an"
"..'an"
"..'an"
"..man.."
"..man.."
"..man.."
"..article man."
