Hiya, I have the same problem.
. I tie a wide cotton scarf to the elbow joints that are still in place from having the double seat on top. When I'm not using it, I wrap it around the handle bars. When I need it, I drop it down so it hangs all the way from the handlebars around the back of the double seat. Added bonus that it helps him sleep.
Makeshift, but free!
