Thanks, Scary - DS is better now and isn't needing to use the inhaler nearly as often, still a couple of weeks to go for us but we'll take it along to the test just in case.
I recognize the symptoms you describe for your DS, as I've suffered from that "morning hayfever" thing myself - I think it's to do with dust mites in bedding (not that I'm suggesting your house is dusty
but these things tend to happen in all houses). My own theory (not medically proven
): when you get up in the morning you inevitably move the bedding around which throws any allergens that have settled during the night up into the air. On the occasions when I've suffered from this I've found it helps not to go back into the bedroom at all for a couple of hours after getting up. I would suggest that your son vacates the room as soon as he wakes up and gets dressed in a different room where his clothes are waiting for him, and doesn't go back into the bedroom at all, if he's forgotten something then it can be fetched. As a further precaution, the day before a test it might be an idea to vacuum the mattress and change the bedding so that the allergens don't get a chance to build up. You can also get mattress covers like these http://www.snugnights.co.uk/dustmites.htm
- don't know if they help but I can see the logic.
Good luck and I hope your DS gets over his sneezes!
