Today I kicked DD2.
I'd had an awful morning - DD1 had got herself stuck down the side of DD2/3's bunk bed at chest height, with just one toe on the windowsill. DD3 had dissolved into tears because DD2 got dressed before her so was the 'winner'. DD1 got a shock from getting stuck and was a complete mess so we were running late.
It was 8.20 and DD1's bus comes at 8.20 then we need to hot-foot it to the school. DD2 had, as usual, completely blanked what she needs to do to be ready for school, and was sat on the sofa using the IPad. I asked her to ready herself. She ignored me.
I had my hands full of lunch boxes, book bags, etc., and I used my free hand to take the IPad from her - by this point she'd had 3 requests to turn it off, all acknowledged by ignored. Instead of letting me remove it, she started to tussle with it. It was precariously close to flipping in the air.
I raised my foot off the ground and kicked her just above the ankle 
I can't believe I did it. I don't think it physically hurt her (she didn't show any signs of it and I would say it was a 'tap' if that didn't seem to be trying to minimise it - I'm not minimising it, but an accidental kick would be much harder than the kick I did...if that makes sense).
I apologised straight away. I told her I'd lost my control and I shouldn't have done it.
Anyway. Roll on tonight and she says that she had to do her 'feeling chart' at Dragonflies this afternoon - they draw in a 'blob' - and she drew a broken leg and a broken arm in hers, because Mummy kicked her on purpose. She said that the others had to raise their hands if they'd ever had that 
and she told me that I should have 'had a breath'.
She told me that she didn't tell them why, or what happened, or anything else. Then, she pointed to her knee, where just below there is a bruise (browny colour, not new) and said 'that's the bruise!'. So goodness knows what school thinks of me now.
