well, what i mean is, how to change a baby, while traveling, when you are mostly walking and want to avoid using the public changing stations in the restrooms. luke and i came up with a great team system in chicago.
step 1: we find an alley or a plaza or anywhere we won't be knocked over by fast-walkers. 2: luke squats and makes his legs as flat as possible. 3: i lay mateo down and begin changing him while he looks up happily at luke. 4: i grab the camera mid-change while all the happy-gazing-at-papi is going on. 5: i finish changing him and taking photos hopefully before an accident happens directly on luke.
this system really worked for us!
