Thanks for the suggestions! Interesting that you mentioned bandaids specifically...I did have those in my bag last year, and I think it's the only trip I've ever needed them. We were eating lunch at Carthay Circle and DH accidentally dropped his water glass. It shattered...right at DD (who was sitting in a high chair at the end of the table). Miraculously, she didn't have a scratch...she was startled, but not hurt. A manager came over to see if we were OK, and as I was about to say "yes" I noticed I had a cut on my finger. I grabbed a napkin to put pressure on it and there was a piece of glass stuck in my finger. Ouch! I thought I could get it out, so my mom and I went to the bathroom...there was a woman who had a pair of tweezers in her bag, and she was kind to let me borrow the tweezers to get the glass out. It wasn't a bad cut, just a bandaid needed at that point, which I had in the bag!
We ended up saving ourselves the trip to First Aid for something rather minor. The manager did mention it to us if we wanted to have it looked at, but my parents are both RNs and we were all confident it was fine. The CM was fantastic, though, in how she helped with the cleanup and took care of us at that point.
I think bandaids will likely be in our bag..just a small, light travel size amount, but they'll probably be there...anything bigger/more serious we'd definitely go to First Aid for...I'm not carrying a medicine chest around with us!

Thank you again for your suggestions!
