I just got a text from my mom asking me if she wants to go over her house next weekend for my BIL's birthday Saturday or Sunday. She lives about an hour away. There is a good chance that I have to make a multi-overnight trip for work either this week, meaning time away from 13 week old DD. I really just want to stay home this weekend and have time with just her, OH, and me.

The dinner is just my mom, my sis, BIL, OH, myself, and our LOs. Sis and BIL only live fifteen minutes from me. I would spend less time cooking dinner and cleaning then I would travelling to my mom's. We'll also be seeing everyone on Thanksgiving. And I'm a better cook!

FWIW, we don't celebrate my birthday or OH's. The only adult birthdays we do are my sis and BIL and this isn't a milestone birthday.

Should I politely decline or offer to host instead?
