Our first camping trip as a family of 5, any last minute gear checks?

Leaving Friday morning for 2 nights. We've got a big Coleman tent, sleeping bags for everyone, and I'm doing all meals in a camp cooler. Just realized I forgot to grab more propane for the camp stove so that's happening today. The baby is 18 months so I'm mostly worried about keeping her entertained and on some kind of schedule. Campground has a lake and hiking trails. What am I forgetting?
