What to pack for a weekend trip?

I am a FTM and going away for a weekend trip in a few days with our 5 month old son. It’s our first ever trip, we’ve never even been out of our town for more than a few hours so I am stuck on what to bring and what not to bring. We won’t be spending much time in the hotel room besides a nap or two and bedtime. We plan to go out and about most of the time or at least that is the expectation we have lol.

Any advice is more than welcome! Thank you 😊
