Sophie is trying to be a big girl, so Mommy let her start the day in big girl panties. Unfortunately, Little Sophie had an accident and peed in her pretty new undies! Ooops! Looks like it's back to diapers! Sophie tries so hard to stay dry so Mommy will let her try big girl panties again, but Oh NO! Sophie not only WET her diaper, she had a MESSY ACCIDENT too! Looks like she'll be in he diapers for a LOT longer!
