Look mate, I always ask people who give me crap to tell me why I SHOULD. They usually have nothing really to say except they think I should do it, or maybe the '"they might catch chicken pox". My answer to that is that every child I know that has/had CP WAS vacc'd and I cant see the point.
I also don't mind if the do catch things like Measles, Mumps (they already got it!) or CP, I think they are better off catching them whilst they are young so they have PROPER immunity when they are older and things like Mumps and CP can be far more severe.
I also had a folder with information on hand to give to anyone.......but no one bothered to read my research.

When it came to MCHNs and Drs I was happy to discuss the issue, although none of them seemed to be able to go further in conversation other than, 'you should do it'.

The kids are older now and no one hassles me anymore.
