She's nearly 8. She says she just 'blanks out' and can't remember anything when she snaps out of it, as though her mind 'opens and everything whooshes out'. It scares her, she says she feels different 
Last time she mentioned it, I thought it was just dd being dramatic (she can be) or describing a perfectly normal moment of spacing out....she's got a busy mind, I can imagine it needs a rest from time to time! But tonight I could tell she really was anxious about whatever it is, and I'm thinking I might have a chat with my GP.
Thing is, all I've read about Petit Mal (my uncle used to have it as a child) indicates the person who has it doesn't realize or remember it. dd seems very aware. I just wondered if anyone has a child who has described something similar?
