Shreiking 5 year old.

[Millarkie]

So do other 5 year olds make incredibly loud shrieking noises at regular intervals or is it just mine?
I'm hoping it's a phase but it's been going on for months now and now his little sister has started to copy him. It's a headache inducing nightmare especially when he's unwinding after school (it seems to be a 'relaxation' thing for him).
I'm getting a little worried that it's just not that usual because he also has a unusual personality (has been put into special classes at school because of his lack of 'application' although his reading level is normal) but I don't know what other 5 year olds do in the privacy of their own homes (as far as I know he does not squeak, scream or shreik at school - in fact he barely talks there).
So, is he letting rip at home after keeping schtum all day? Is he a totally normal irritating but ultimately loveable 5 year old? Or should I be getting more worried?

Can only speak from my experience of ss when he was 5 here, and can say, no shrieking, but he did develop label phobia at this age and we had to cut them all out of his clothes he had to go into special needs reading as well, but that was due to him being bored, not the fact he couldn't read as they discovered rapidly. Hope someone comes along with better advice than me soon, but didn't want your post to go unanswered.

let him play in the garden for half an hour after school. Tell him to get all his shrieks out, be4cause they can't come in the house.

Thanks Frizbe.
Ds has definately got an unusual personality but I've been hanging onto the belief that it's just who he is, and school hadn't mentioned anything except for the extreme shyness mixed with extreme liveliness.
He is incredibly variable in his work, often just refuses to do it, but sometimes will sit down and write a full page, He freaks out if he has a supply teacher ( I can tell from the moment he leaves the classroom without having to ask him) he has incredible violent tantrums at home still but since he doesn't do it at school I thought that it was OK. But now school have started to point things out and give him extra help and the squeaks and screams are getting me down.
We haven't had label phobia - yet
We do have phases of obsessions - like checking every parked car on the school run to see if it has an immobiliser light or a crock-lock or nothing.
Oh, I don't know - just not sure whether I should be worrying about getting him more help.

I do feel sorry for our neighbours

Don't have a garden to use Colditz
He doesn't shriek as much outside - but to be honest it's bl**dy loud and the neighbours would hate us even more.
Maybe I should get him a school boy sized dummy
Sorry, it's late and I'm swinging between worry and embarrassed humour.
