Help me find a book?

[swg1]

My toddler is after me to find "the yawning book". Apparently this involves a bear, yawning, and possibly Thomas the Tank Engine though I'm honestly not convinced he hasn't mixed up two books. Also a dark blue cover. I've been hunting and I honestly have no memory of this book even existing. Help?

Not the rabbit who wanted to fall asleep ? There is lots of yawning in that.

No, we definitely don't own that one because I remember looking at it and not getting it!

Sleepy Bears has a blue cover

Can't you sleep little bear?

It has dark blue on the cover

Peace at last by Jill Murphy?

Bear Snores on (or something like that)?

Hugless Douglas? He wakes up from hibernating so does lots of yawning and stretching!

Don't wake the bear hare?
