Sunny's Step-Mommy is trying to potty train her. She doesn't usually have accidents during the day, so she's been allowed to wear cute little Pampers during playtime. When it's time for bed, Sunny uses her potty chair like a good, and then Step-Mommy Luna lovingly changes her into a much thicker nighttime diaper. Step-Mommy's still needs extra protection while she's resting. Sunny looks so happy to be on the changing table getting put back into diapers!
