can you transition into a bed now? would that help?

otherwise, I'd also just try tucking the sheets very tightly, to see if that helped ...

in the recent hot weather, we just stopped using sleeping bags (because it was too hot) and haven't gone back to them - but DS wasn't using the bag for day sleeps, so it hasn't been to big a change ...

I have one very big sleeping bag you could borrow, but it's probably too thick ... want me to bring it on Monday for you to have a look at?
