Whoops, I thought, at 7pm this evening when I first saw the linky idea. Today is the 10th! So with a sense of foreboding in my heart, I thought I'd give it a go anyway, after our youngest got out of the bath.
If I'd have used my crystal ball I could have seen that this exercise would pretty much end in tears but it's all OK, they said sorry to each other (there was a misunderstanding over what constituted a dance pose, with Sasha insisting that was Superhero and Tamsin really should have plumped for something more like Irish Dance pose number two...) and are now sleeping soundly.
Phew. Glad that's over for another month.
