You see, my niece Emma (who will be 2 next month) has for whatever reason taken a strong liking to me. I don't see her too often so I'm sort of at a loss for where her attachment comes from. I'm thinking it may be very strongly linked to the piggy back rides. Anyway, my sister and I are sitting in the living room when she tells her mommy she's got "poo poo", which translates as needing a diaper change. So my sister grabs a diaper and wipes and Emma sits down in front of me. My sister drags her over, lays her down and she fusses and squirms while calling out," MB.. MB..", which is what she calls me. So my sister lets go and Emma squirms her way over till she's in front of me and throws her legs up with this huge SMILE on her face. It was as if she were saying, "Congratulations! Moms been stripped of her privileges and I have offered you this once in a lifetime opportunity. Isn't it exciting?" So of course I changed her diaper. Not to mention her mommy was all too willing to relinquish her diaper changing honor. Luckily it didn't end up being a poopy diaper.
So to summarize, most of us consider diaper changing a pain. But it the eyes of a 2 year old, it's apparently a privilege.
