DD is 8
She's slim and reasonably active - has an hour's swimming class each week, walks to and from school, does karate. Plus we go swimming as a family, and she does the usual running around at cubs etc.
She's just started doing junior parkrun though and has been crippled by stitches - has to walk half of it.
Today we tried only a small breakfast and well in advance. I also tried to explain the trick of keeping breathing out of sync with the feet. But it didn't seem to help.
Any suggestions? I think she's keen enough to keep trying and see if they gradually go away as she gets used to more running.
If it were me, I'd go no breakfast at all and run fasted, but I don't know if that's realistic for a child!
