Serena may still be hanging onto her paci but, she's very proud that she has graduated to the pull-up diapers for "Big Girls" and she wants to show them off. She's giddy with excitement as she shakes her crinkly little butt and farts her stinky farts right in the diaper like the big girl that she is. She can't help but let some of her farts out and take in their noxious aroma until she remembers her status as a big girl again and puts those farts right back in her diaper! (WMV)
