Little U is four and a half years old. She cannot talk, and doesn’t understand much of what other people say to her, so she often finds the world a frightening place, especially if her big sister B (who also cannot talk) is being upset.  (Actually, U, a sensitive soul, doesn’t much like it if anyone is upset or shouting near her, but her big sister is particularly frightening.)

U likes music, and she can follow different versions of the same tune through different voices, different musical instruments, even different keys.  Late at night, U can often find a space to curl up on her daddy’s lap when he is playing on the computer, and this is nice and comforting and safe from her scary big sister. 

A few months ago U decided that there was a particular thing to see on the computer that she especially liked.  It starts with a nice man saying what sounds like some comforting words, and then there is music, and pretty pictures to go with the music; and the music changes interestingly and yet remains the same, and the pictures change too but they get prettier and prettier, and are also very interesting and soothing to watch. (Near the end it gets interrupted again by some more people talking, but then it comes back.)  U often falls asleep on her daddy’s lap watching this particular web page.

The web page in question is here.
