Tiffany quietly slept in her crib sucking on her pacifier. The suckling noise was quite loud as she was new to being a baby after 16 years of being grown up and her mouth was not used to the unusual shape of the nipple on the pacifier and hence the loud suckling of it.
Katie had made sure she had Tiffany's hair put back into pigtails before putting her back into diapers in the changing room and insuring that the diaper was the only thing that Tiffany was wearing and the blanket was the only modesty she had as she slept in the crib and it clung to her 16 year old curves. If you pulled back the blanket, you would get a lovely view of her fantastic breasts.
As she slept, Tiffany squirmed a bit in her crib as a flow of urine streamed its way into her diaper shortly followed by a couple bowel movements and they quickly lumped up as they exited her ass and mushed themselves against her butt and expanded and filled the diaper. The smell quickly traveled out the crib and down the hall to where Katie was changing in the next room over.
Shortly thereafter, Tiffany started to cry loudly to have her diaper changed. "WAAAHHHH! Me go poopie in my didee! WAAAAHHHH!"
