Just wondering what people would do in this situation...

DH's grandma went into the hospital with the flu on Sunday. She's feeling better today, and will hopefully be released either tonight or tomorrow. Every year his family has their Christmas celebration at her house on Christmas Eve. DH talked to her today and she wanted to know if we would be coming. She still wants people to come over.

Everyone will be bringing all of the food and drinks needed for the celebration, so luckily it won't be a big deal for her to still host.

My concern is that we have two little kids, one of whom is an infant. She's six months old, so she received her first dose of the flu vaccine, but hasn't received the second one. I'm very nervous about exposing her to the flu. DH is going to go to the celebration wither way, because he feels it's important to see his grandma. I'm okay with that and would just stay back.

In our situation, what would you do? Am I being too paranoid?
