Now THAT's funny! I'm curious... do you use that blanket to tuck them in at night or to make their bed a little softer? Do they sleep on their backs or stomachs?
Seriously though... you know how you have to try a lot of different things sometimes in order to get snakes to eat. Sometimes separating them helps, but sometimes putting them together helps. As the folks from the Netherlands say, "seeing eating causes eating." Just cut the worm pieces fairly small, and keep an eye on them but remain still. You'll have to keep experimenting with different techniques and different food items.
