Hearing about the Swansea outbreak makes my heart go out to those parents as my DS had measles last year and its a really hard two weeks for all the family.
The worst thing I found is a lack of public information, or even medical advise around about how to care for your child if they do catch measles - its as if no one knows what to do anymore.
My son caught it (despite vaccine) and I really struggled to find information, and my Mum couldnt remember what to do - until someone loaned me a book which had loads of useful ways to make the child comfortable - its by Wendy Lyall called "Raising a vaccine free child"
It recommended letting the fever burn out without calpol, a long recovery period - once their spots have gone and keeping them in dim light even once the spots have gone - as otherwise their eyes can be damaged. I got sunglasses for my DS as even when we left the house weeks later his eyes hurt. Also keeping the child warm at all times is really important - not even letting them walk on a cold floor.
Anyway if anyone wants to talk I can share my experiences - as its really difficult seeing them being so ill and uncomfortable and that cough is awful.
