Since moving ds into his own room he's had some beautifully timed illness and teething so I've found myself still sleeping with him most nights for at best a couple of hours and at worst the full night. I've just swapped my nice comfy bed for the floor in his room 
Hopefully this won't go on forever but I expect occasional recurrences so want to get a decent comfy solution in place thats easy to sort at 2am without having a massive spare duvet stored in the nursery for me to sausage myself into (current solution)
What do you do?
