Weekend trip with baby

We are traveling out of state with our 1 year old for the weekend. We will be gone Thursday night through Monday afternoon. We’re leaving Thursday afternoon, driving about 4 hours, staying at a hotel, and then driving the rest of the way on Friday morning. This is our first time going on a trip with him, so I am nervous on what I need to bring, I don’t want to bring too much and am prone to overpacking 😅 Any suggestions or advice?
