ds's whole body jerks

[Calally]

ive been noticing this more frequently. when ds is almost asleep, his whole body jerks/shudders. he had febrile convulsions when he was younger ( he's 6 ) his used to do this just before he had a convulsion. has anyone else experienced this, or could there be something wrong?

Prob nothing to worry about if it is only at going-to-sleep time (we all do that sometimes apparently).
My ds was having these throughout the night every 2mins, I was beside myself worried sick about epi;epsy.

It turned out gluten antibodies were destroying his brain, we went gluten free and the jerks have stopped. Prob extreme situation in our case tho.
