Stacy,
Camping is wonderful! We love to go spend a few nights out and it is a lot more economic than hotels and such. If you google "camping basics" then you will get tons of articles that range from simple to more in depth. We have camped at Joe Pool Lake (Grand Prairie), Lake Texoma, and Lake Murray (the last two are in southern Oklahoma) to name a few.
Try to get a campsite close to the bathrooms if you can to make the middle of the night trips easier if that is a concern of yours. We always take air mattresses, camping is supposed to be fun and we would rather not sleep on the ground since my husband and I have had our fair share of that in the military! Sleeping bags are a must, if your child(ren) is small then a pack and play is great for them to sleep in. Cooler with drinks, sandwich stuff, easy food is best if you are new to the whole thing. Bug spray, flashlight/latern, firewood if you want a campfire since a lot of places forbid gathering firewood on site. Most of all... have fun!
