I'm 5ft 10 and didn't even think about that! DH is tall as well. When I think about it, I picture us just grabbing the organizer thing and throwing down a prefold and changing him wherever we are. Like I said, we are in a small space so I wouldn't be going more than.....15 feet to grab the organizer, wherever it is.
Of course, when I picture things, Nolan is also the easiest baby in the history of babies and never cries or pees on me.
