It never fails to amaze me how children can sleep almost anywhere when they feel like it.
Twin girl is a master at this, but I did think that by the time she turned six she might have grown out of falling asleep in odd positions/places. Her twin brother always goes and tucks himself into bed if he feels tired, which is far more sensible (and means that I also get the sofa to myself).
After a particularly heavy week at school (apparently Year 1 is really tough) I found her like this on the sofa one Saturday afternoon. How she didn't slide off I have no idea.
Of course, she stayed up for ages that night, but that's another issue for another blog post. *sigh*
