Tailgating with 3M Newborn?!?!

I’m at 34 weeks pregnant/ a FTM + some of my family and friends want me to plan to attend a tailgate in early September, when baby should be about 3 months. I am planning to BF. My one family member suggested I get a baby sitter for the day— Am I the only one who feels like that would be the last thing I’d want to do? I really cant imagine leaving my baby for the sole purpose of going to binge drink at a tailgate! I understand the need for baby sitters for certain occasions (eg work, adult-only weddings etc) or even a date night, but it just seems like it would be really irresponsible to get one for a tailgate, IMO.

If I went, I’d bring baby and absolutely limit drinking. However, as a FTM, i have no idea what to expect at 3 months. I’d be worried about her overheating in early Sept, how I’d BF in front of people (that’s something I know I’ll need to get over quickly), etc etc etc.

Since I’m going to be new to this parenting thing, I’m just wondering if I’m being reasonable here or not ... I don’t think a few family members and friends will “get” a lot of parenting stuff at first so I think I’m going to need to be more assertive/setting some boundaries.
