Amusing Arguments About Guest Lists

Guess who is apparently sending one invitation to my fiances uncle, his baby mama, his kid, and his girlfriend? That's us. 🤦‍♀️🤦‍♀️🤦‍♀️ I told the fiance this was stupid. But the FMIL insists baby mama has to be invited. TBH, girlfriend may be accidentally forgotten. What the dang heck?

After seeing WAY TOO MANY people on this forum say "just dont write the kids names on the invite, don't say adults only" I'm glad to know I was right in thinking this was terrible advice. I asked the fiance how to spell his 4 year old cousins name so I could put it on the save the date. To which he told me "she's a baby, you dont have to invite her. She will just show up with her mother."
To which I reminded him that we are doing online invites and have to have every invited guest listed on there. And that we're probably doing assigned seating and her 4 year old butt will need a chair so she can avoid sitting in it.

Wish me luck.

We're going to a wedding in November with a formal dress code. (I've never heard of such a thing really.) But I'm hoping he & my future in laws get a tiny bit of culture shock and start realizing I'm pretty chill about this wedding crap.
