The bedtime routine for Eva involves singing appropriately soothing songs for about twenty to thirty minutes - And "Twinkle Twinkle" is only a couple of minutes long, no matter how slowly you sing it, so you either have to sing it on repeat, or come up with something else.
I remembered a fair number of other lullabies, but not a huge repertoire, so then I moved onto a selection of songs from "The Sound of Music" - This is odd because it's not one of my favourite musicals and never has been, and yet I know the whole "Favourite Things". Doc C has never seen the film (or stage version), so he thinks my rendition of "Edelweis" is lovely, and it seems to have a suitably narcotic effect on the kidr.
Now I've gone a little more classic jazz musical by adding a few Cole Porter standards ("You Do Something to Me", "Miss Otis Regrets", "Don't Fence Me In" are the most frequent) along with "One for my Baby (and One More for the Road)", which is perhaps not the most traditional of nursery rhymes but it does the job.
This evening out of nowhere "Diamonds are Forever" made an appearance. It's come to Bond themes now? Oh dear.
