I'm prepared to be told IABU, just feeling a bit fed up really.
DSD had a heart attack a few years ago, and is now very twitchy about his health. This I can understand, but to such a degree that he and my DM will happily miss important family events if there is so much as a sniffle in the vicinity. Tonight was my DS's first birthday party, and due to DD (10yrs) having a vomiting episode and taking to bed after school, they have decided to swerve the entire thing.
I feel that other grandparents would want to celebrate regardless, and there is probably more risk of catching something from a trolley at Tesco than a child not even in the same room. I get that he's nervous about sickness, but due to having three school age children...it's unlikely there will be an event in the forseeable future that doesn't involve at least one snotty nose!
