I carry basic first-aid supplies when we go camping with the kids because I was a Girl Scout and I am a Mom Who Likes To Be Prepared.
Here is my list, followed by photographic evidence of its inadequacy.
OFF!® (not pictured), Saline drops, and Syrup of Ipecac (but I'm afraid to use it and thank the Lord I've not had to). Sunblock of course is always with us, and this time I added Tums because Shark Boy is obsessed about tummy aches right now.
Another tip! Bring wet wipes.
