Mine had a blood test earlier this year, got all the coaching on what they were going to do, what she should do etc etc.

Unfortunately she decided several seconds *after* the needle went in and the doc was halfway through getting blood that the needle going in hurt, so she did an overdramatic jump complete with exaggerated facial expression, needle comes out, blood goes everywhere, doc goes into panic mode.

Started again on the other arm with me holding her down, worked this time.

Reminded me a bit of the time she got her nose cauterised - screamed the house down when the cauterising thingy was an inch from her nose but didn't even blink once it was actually in use. Needed two of us to hold her still and she hadn't even been touched. The doc looked like she was going to wring DD's neck.

So watch out for kids doing stuff you don't expect ...
