Just in case you were wondering how I do it with two kids on the airplane. It's always better when William has his own seat. Truth be told, I was informed it was going to be a full flight - if I'd had known William would have his own seat, I would have brought on his carrier car seat. Early flights on Southwest are the BEST - even if that means getting up at 5:30 am to make it to the airport.
On the way back we had a little different situation. William had a blow-out right before we went through security. I luckily had my sister Alli and my Mom there to help me. (Alli even got a gate pass so she could hold onto Sarah while I made my way through the security process. I have to say it was a BIG help.) We stripped William down to his diaper. I had forgotten to pack an extra onesie. (Of course) I also forgot to take out my portable dvd player so the security guard had to open my backpack. Again, I was thankful Alli was with me. It's just a different monster when you have two kids, a stroller, car seat, bag, shoes, etc. to worry about.
Once "on the other side" we said goodbye to Alli and headed for a gift-shop that would have something to clothe my youngest child in. Much to my dismay they didn't have anything worth buying and I had the unfortunate experience of purchasing a basic onesie with the saying "Potty Like a Rock Star Las Vegas" on it for $16. Lesson learned. Expensive lesson, but learned none-the-less.
Oh and for the record, I don't think I'll be traveling by myself for quite a while. William didn't have his own seat on the way back and Sarah is quite fidgety when "all electronics must be turned off" at takeoff and landing.
