Don’t want to bring 5 month old to Thanksgiving?

I don’t want to bring my baby to big gatherings until he gets to be 6 months. But my entire family is mad at me and text me about how mad they are any chance they get. Mainly because I have a lot of other family members with babies mine’s age or younger that are coming. I’m worried about him getting sick and so is my husband. I told them repeatedly I’m coming to Christmas which isn’t but 4 weeks till after Thanksgiving. And it’s a one hour drive to get there then a one hour drive back. I told them all today that their willingness to not be understanding is actually what’s making me not want to come even harder LOL. Am I being a jerk? I feel awful but we’ve been planning since before he was even born not to come to Thanksgiving so they’ve known for months and just assumed I would change my mind. I love them so it’s nothing personal but they’re taking it that way.

Also I even said we can host at my house with just the closest family and that’s not good enough either. All they care about is the Facebook picture.

Edit: I’m sorry I really didn’t explain my reasoning which would make a lot more sense lol😖😖 my husband’s dad just recently passed away in a traumatic way from an illness. So he is very over protective over our baby and I think in his head he’s trying to minimize him getting sick as much as possible so I’m trying not to push him on it (he truly just needs time to grieve and sort out his feelings) The only reason we’re going to Christmas is because he knows it means so much to me. Also have anti vax family members ☹️
