Playing House

I crossed my arms over my chest in disappointment. 

"You're still dry, Nina?  This is disgraceful!  Get up into your crib this instant!" 

My sister looked up at me with a pout and and crawled into the crib, facing the wall and bending over just the way she did with Mommy.  I reached under her bottom and pushed on the seat of her diaper. 

"Go ahead.  Use your diaper." 

"I dun wanna play anymore!" 

"Shush, Nina!  I'm the Mommy!" 

Despite the thick diaper taped around my hips.

-

"You can't be the Mommy when you're a baby too and Mommy said I don't have to listen to you and Mommy also lets me use the potty for pushies okay so stop being mean! Or I'll tell on you!" 

Bad enough that I assumed the position on her command, but that was just habit.

-

I puffed out my cheeks in frustration. 

"Nina, you aren't playing right!  I'm the Mommy - I called it!" 

I went over to the changing table and grabbed one of our nighttime diapers, unfolding it and returning to my sister. I put my hand on her bottom again. 

"Now you fill your diaper for Mommy this second, or you'll get a very harsh spanking!" Nina always hated spankings. 

"Excuse me?" I nearly jumped out of my skin, spinning around to find Mommy in the doorway.

-

"You called it, huh, Anna? You called being Mommy? And I suppose that's all you think it takes? You think Mommy is just a name and a title, is that it?" 

I watched over my shoulder in awe as Mommy approached my sister, four big strides was all it took for her to be upon her, finger pressed to her chin.

-

I took two steps back and bumped right into the crib, but Mommy had my chin in her fingers and pointed my eyes up at her.  Though she was only a few inches taller than me, with her so close, I felt like I was no taller than three feet. 

"W-we were just playing House," I muttered, blushing. "I didn't mean it..."

-

"It sounds to me like you were trying to make your sister put on a smelly little show for you. Sometimes, Anna, I wonder about if maybe you like using your diaper a little too much. I think from now on... no more potty for pushes. Nina can continue to, but I think you're going to take up a new role in the house. As the baby sister." 

Mommy smiled and looked up at me. 

"I hope you're going to be a good big sister, Nina, your baby sister Anna is about to need a change.
