I know one gf who was really concerned and asked everyone at preschool last year if they had been in contact with whooping cough and/or had been immunised. She's a dr and a little paranoid!

I don't think I'm going to have the option of worrying next year - DD goes back to school when this one will only be about a month old. So I guess I'll just play it by ear. I don't remember being particularly concerned when DD was tiny, but we weren't in contact with as many other young kids then.
