Thank you Caz. I appreciate the info. Whilst the little boy is getting over his croup, dd has been off school with an awful cough too (but not a croupy cough), the man has been suffering with an awful cold/throat, and I have a very sore throat!

I thought for ds that it had to be quite climate related as. He was always sick at the old places (so were we all, this is the first time we have been sick here, since october, and that's a record for our family.). We had a bit of a cold spell here just before he got croup too.
