Anna poops her diaper.

As Elsa loaded the last spoonful into her cousin's mouth, wiping the girl's face with a napkin shortly after, Anna lost control. Anna froze in horror as she loudly pooped in her high chair, the dam breaking as the warm, hot, icky mess poured into the seat of her diaper. Her whole body turned red as Elsa threw the finished jar and napkin away in the diaper pail. Rapunzel placed hand on the princess' shoulder and gave her a reassuring smile. Anna was not as accustomed to being a baby nearly as much as Rapunzel. First time Anna pooped in her diaper, she lost her composure completely and cried the whole time, embarrassed beyond all reason. She was surprised when Elsa asked her if she wanted to continue their sessions, as she thought Elsa was disgusted by the whole thing.

Elsa brought the second jar of apple sauce over and placed it in front of Anna, ready to feed her sister. Anna was still completely frozen and red. Elsa scooped a spoon full of apple sauce and brought it up to Anna's mouth, whole did everything she could to not look at her sister.

"Come on baby girl. Open up for sissy."

Anna looked down at her onsie, the outside looking clean and unassuming. On the inside however, she could feel the mess in her pants spreading around between her skin and the padding of her diaper. Elsa was acting as if nothing happened. The baby oil perfumed the diaper, masking the scent well enough, but not enough not to be noticeable. Anna let a few tears slip through.

"Oh, don't worry baby," said Elsa, who got up and wrapped her sister in a hug. "After I feed you I'll have you changed into a brand new diapie. Your big sister is here to make her baby sister all better, because that's what big sisters do."

Anna was still crying, but she shook her head, understanding. Rapunzel stuck her pacifier back into her mouth as she sat back and watched Elsa feed Anna. Anna's crying slowly subsided as she accepted the mush into her mouth. She did not taste a thing, wanting to be out of her own mess as soon as possible. Before long, the jar was empty and Elsa unlocked the highchair, picking her baby sister up and carrying her to the changing table. Anna had her arms around Elsa's neck where she buried her face. She felt the mess in her diaper spreading more as she sat on Elsa's arm.
