True story..my little one likes listening to film soundtracks at bed time. Ds9 is one of his favourites. I have ‘lullaby’ that is basically me singing the names of the characters to the theme music, which I sang to him regularly to help him sleep. ‘Sisko and Jake, and kiiiira...Rom and nog, Quark and Bashir...Kira and Dax...and Oooodoo they all love on Deep Space Nine...’
On a good day I could get them into little familial groupings, and yes, I include Keiko, Yoshi and Molly too.
I also have a version of old MacDonald but with people from Voyager.
Sadly he has grown out of these songs.
