Should I travel to my best friends wedding with my 8 week old?

My best friend of over a decade is getting married in a little over a month and my newborn will be 8 weeks. The wedding is a little over an 8 hour drive and because of where it’s located, flying wouldn’t be a better option and we would still need to drive a good amount. My friend also didn’t decide on a wedding date until November so I haven’t had a long time to know about it either.

The wedding is on a Saturday and we wouldn’t be able to leave until the Friday afternoon which means we would get in really late Friday night then we would leave Sunday so my husband could be back for work Monday. Unfortunately, my husband doesn’t have the option to take work off Friday or Monday.

I am worried about our baby being in a car seat for so long and know we would need to stop at least every 2 hours. I’m also only breastfeeding and she won’t have her two month vaccines yet.

I would feel horrible missing the wedding but I’m really having a hard time deciding what to do. I’m the first of a lot of my friends to have a baby so many don’t understand.

I’m really just asking for advice and if you have travelled this young for some insight. What would you do if you were in my shoes?
