Cassie felt a baby was a tad too young for her so she decided to age herself up a year.
“I wish I was a toddler.”
She waited a few seconds and felt her body start to mature and grow a couple of inches with her losing most of her baby fat. Her diaper also grew a little continuing to fit her even as she entered the realm of toddlerhood, remaining as snug and secure as ever around her waist.
“There we go, all done!” her mom said remind Cassie she had just been changed and was still lying on the table.
“Yay I got a new diapy” she giggled happily, rubbing the front of her padding between her legs with her hand and giving a slight kick of her feet.
With her older age Cassie found herself now able to speak though with the added bonus of a lisp.
“That’s right Cassie because mommy just changed you” she replied with a big smile at her baby girl's response.
Her mom then reached under her armpits before lifting her up and setting her down on the floor.
“Now you be a good girl and play while mommy does some work around the house, ok?”
Cassie nodded her head before sticking her thumb in her mouth. She sucked on it as she watched her mother leave the room and once she was gone decided to check out what she looked like.
“I wish der was a miwor” she said and a second later a full-length mirror appeared on the nearby wall.
Toddling over to it (for wishing to be older had given her the ability to walk again) she looked at her reflection and saw an adorable two year old girl staring back at her.
‘Holy cow I never knew I look so cute as a toddler in diapers’ she thought as she continued to gaze at her infantile beauty, ‘Hmm you know what I think I’ll stay this age for the time being’
Being a toddler was perfect for her as she was not too young as to be helpless, but at the same time not too old as to be without the babyish garment on her behind.
Cassie admired herself in the mirror, turning around a couple of times to get a good look at her crinkly rear end. Seeing the sight of her disposable underwear always made her happy and caused her to do a little dance which ended with her sticking out her padded butt at her reflection, giggling as her reflection copied her.
However like any two year old she quickly became bored with her current activity and wanted to do something else.
