I've tried other songs at bedtime, but the only one that has stuck is Hotel California. I don't know why I picked it up in the first place -- I don't care much for the Eagles -- maybe because it is long and has elements of repetition in it, or because I can somehow remember the words. Regardless, I've been singing it to Jack since he was a baby.
The song is actually quite adaptable to variation. I simply replace about half the nouns with other words, keeping to a theme. One of Jack's favorites is preschool buddy California -- with the nouns replaced with the kids from his (now former) preschool class. A few nights ago I did a Legloland California version that was smashing.
Last night we did 3 versions: preschool buddy, Legoland, and regular (original). Jack interrupted me to ask, "what exactly is colitas anyway?" (pause) I answered, "it's a plant and sometimes people like to burn it," (not a lie!). He was satisfied.
I think I need another rambling song for bedtime... any suggestions?
