Song: Wind the bobbin up.
It's a song.
It's a nursery rhyme.
Is that still sung?
A regular feature of my childhood.
Not a regular feature of my childhood.
Never heard of it.
I wound actual bobbins when I was a child.
I wound actual bobbins when I was a child while singing this song.
You may sense a theme in recent polls.
Edited to add: Early days yet on this poll, but given the song's ubiquitousness in local baby-oriented singalongs around here, I thought it was a standard feature of English childhood which C (who's from Lancs.) had just happened to miss out on. I'm glad I asked since it may be either fairly recent or relatively local. I await further data.
