I'm finding it hard to imagine what it looks like - are you saying its developed a tallish main stem with all the growth coming off that? What about doing leaf cuttings and starting a few more, then just cutting back the one you've got if its gone all floppy. Is it a trailing type anyway?

It has a thick stem over an inch long and the whole rosette grows from the top. I think they must do this in the wild but I've never seen it before. The trouble is that it all leans over at an angle. Not sure about cutting it back as I would be left with a bare stem which may or may not sprout. I do have another offspring several years old now which is also a brilliant flowerer but the first one was a gift and I would like to keep it if possible. It isn't a trailing type - didn't know there were any!

Hmm, difficult then - I wouldn't risk hacking it back unless I'd raised babies from it first.

That's how I feel. Worth asking though!
