Why Do Babies Like To Poop In Confined Spaces?

Let me tell you a story about last night. We head out to Rob and Tara's house with 4 diapers, a container of wipes, and one baby that had already pooped three times that day. So around 7:30 while Tara was watching Bailey and I was cleaning up the dishes, Bailey wandered into the pantry and she pooped. Thus finding confined space number one for the night. Around 8:00 she finds confined space number two: between the wall and couch and she poops. At this point I use all the wipes, but one because she can't possibly poop again. Around 8:30 Luke finds a basket that Bailey would fit perfectly in and would be great for keeping her contained. Guess what? She poops while in it. At this point I put her in her last diaper, and clean the mess up with one wipe. Lucky for us she was done pooping for the day, but why do babies like to poop in confined spaces?
