Can you rent pack mules?

I just realized that I'm going to be the most ridiculous person to grace an airport when I travel with Carter next month. I'll be carrying a kid strapped to my chest, a laptop, a fairly large camera, several tons of snacks to keep the kid happy while we fly over several states, and all the stuff I normally carry. Except a book or magazine, something tells me I won't have time for onboard reading. And I don't want to THINK about all the stuff I'm going to have to check.
