Travel quirks

We are planning a trip to visit my Mom at the end of this month. This will be the first time we have flown on an airplane as a family of four. I'm not too worried about it, since in my former life I was a Gold Elite frequent flier, but I am already dreading the logistics of getting us onto the plane. I am one of those people who always packs way too much, and recognizes that fact. However, I know I will be running around the night before we leave trying to get everything ready for our trip. We will arrive at my Moms and I will not wear even 50% of the clothes I will bring. I will be tempted to pack things for my kids that they have never used to date, "just in case." I will bring back-up outfits for the kids for each day, completely forgetting the fact that my Mom does in fact own a washing machine. DH will also be a nervous wreck, since he hasn't flown more than a handful of times in his life, so he will be basically useless at offseting my anxiety.

I'm sure we will have a good time on the trip, Toddler will be awestruck by the experience since he likely doesn't remember his last plane trip (a year and a half ago), and Infant will not really know what is going on. I just hate the stress I allow myself to feel in the getting ready to go stage. It is not as though we are leaving the country, but yet I will feel compelled to pack three tubes of Desitin despite the fact that even with a really nasty diaper rash we couldn't use that much in 3 months. Why is it that I know all of this about myself, but still let it happen? I used to travel weekly for work, had it down to a science, could pack in less than 10 minutes, never brought extra things because there wasn't room for them in my carry-on. Leisure travel is much more stressful for me than business travel ever was. I will pack so much for this trip that we will risk being charged for oversized luggage. Oh well, at least I recognize the fact that I am crazy, that must count for something right?
