"You know all this talk about diapers has got me more than a little intrigued, maybe I should join you" she said with a raised eyebrow, her voice filled with playful curiosity.
Jeff blinked, not sure he heard her right. "Wait...are you saying you want to turn into a toddler too?"
His mother chuckled softly, the idea amusing to her. "Why not? It could be a fun bonding experience for us and I could definitely use a break from being an adult. Besides it's only for the weekend, right?"
Jeff was completely taken back. While a small part of him found the idea of his mother, the woman who gave birth to him, walking around as a diaper dependent toddler weird, the bigger diaper loving part of him was incredibly excited at the thought. So it was no surprise when a few moments he smiled, "Okay, I guess it could be interesting having my mom as a playmate."
"That's the spirit!" she said smiling as she stood back up. "Now come on mommy's not getting any younger, or at least not yet I'm not" his mother casually joked as she practically ran out of the kitchen with him following behind. Heading upstairs they entered his parent's bedroom where his mother sat down at the computer desk, the program having relocated here when he regressed and his room became a nursery. Sitting down on the chair his mother began eagerly typing away.
"Hold on, what about dad?" Jeff asked realizing he forgot about his father.
"Don't worry I already thought of that. I going to make him a single parent for the weekend. I'm sure that man can last three whole days without me" she chuckled. "Just in case though I'm also giving him a higher paying job that way he can afford a babysitter for us."
Seeing the logic behind her words and she had everything figured out Jeff stood back and patiently waited for her to finish making the necessary changes. After a while a thought came to mind which he voiced immediately. "Hey uh, since you already on it can you do me a favor and make me three months older. I kind of want to be your big brother" he admitted with a blush, acknowledging that she was to be his little sister. "Oh and make sure I don't lose my diapers" Jeff added.
"That's fine, there has to be a bit of an age difference anyway otherwise we'd be twins" she explained then laughed, "And don't worry your diapers are safe with me."
A couple of more minutes and everything was set. After setting a sixty'second delay timer they both walked to his nursery and stood in the middle of the room, waiting for the changes to take effect. When the transformation did happen it proved to be just as quick as his own. Jeff watched his thirty-eight year old mother rapidly regress before his eyes, growing younger and younger back into a young woman, a teen, a child. Paying close attention to the final changes he saw her body regain lost baby fat and her face turn cherub-like as she became a two year old toddler. The newly regressed baby girl was dressed in a Moana themed t-shirt and a diaper and had a pacifier in her mouth. She stared back at him as she calmly sucked on it, her eyes wide and innocent just like a toddler's. His changes were less noticable being only a few months but Jeff felt them, only being growing a couple more inches in height and going up a diaper size as the disposable garment grew a little with his waist.
Removing the pacifier so she could talk properly, "Well, this is...something" his mother said with a soft giggle, looking down at her now tiny hands.
Jeff nodded, smiling as he took in the adorable sight of his now-toddler mother. "Yeah I know, it can feel pretty strange." He then couldn't help but ask, "So how does that diaper of yours feel?"
The baby girl's attention was then drawn away from her hands and to the padding taped around her waist. "Pretty good" his mom answered. "It's feels like I'm wearing thick underwear. I do like how it spreads my legs though" she admitted with a cute blush.
Jeff simply nodded. It was still too early to judge since she only been in them for less than two minute. And neither of them had used them yet which was an experience he was looking forward too.
The two then look around and saw the nursery had changed, becoming bigger and now having two distinct wallpapers seperating it into two sides running down the middle. The pink side was clearly themed for a girl with appropriate toys scattered on the floor with a crib against the wall. The blue side was the same having a crib and toys, though it was geared toward a boy. A fully stocked changing table shared the boundary between as both of them had equal need of the piece of furniture.
Amazed by their shared nursery Jeff and his mother stared in wonder for a few more moments before facing each other.
"So what do you want to do first?" Jeff asked with a shrug, leaving the decision up to the other toddler.
