In need of some advice...

So my daughter is exactly one month old, and she wont be getting her vaccines until she’s 2 months old. We have a thanksgiving dinner tomorrow with all of my aunts, uncles, cousins and their kids....I had decided to skip the dinner because I don’t want my daughter to catch anything in case someone is sick, but I feel so bad about not going because my other daughter who is 6 and my son who is 3 are going with my mom and they want me to come too. What would you guys do?
