"Okay mom you become three years old and Natalie you become two years old" Brianna finally decided, "That way you'll still be a little bit older than Natalie."
"Wait why do I have to be younger than mom?" Natalie pouted.
"Because I want you to see what it's like being the youngest for a change" she replied with a smirk.
Her sister crossed her arms and continued to pout.
"Aww cheer up little sis at least you'll get to wear diapers again" Brianna said patting her on the head.
"That's true...but you better not make fun of me for using them" she said with an angry look.
"She won't baby, because I'll be in them too" Olivia promised then gave a stern look at Brianna, "And if she does make fun of you then she'll be grounded for a month when we get home."
"That sounds good mom, but I still feel a little unsure about wearing diapers again" Natalie says.
"Would it help if I told you I like them too?" Olivia says.
"You do?" she asks.
"I do, that was the reason I let you stay in them for as long as you wanted. It was also why I punished your sister so harshly for teasing you because she was also teasing me. Now I'll say it again, there's nothing wrong with wanting to wear diapers" Olivia said.
"Mom you're like the coolest ever" Natalie exclaimed as she gave her a hug which she returned.
"Okay enough talking, are you ready to get young now or what?" Brianna asks getting a little impatient.
The two of them nodded as Olivia and Natalie then focused on being the ages Brianna set for them. They both then began to rapidly regress backward in age their bodies shrinking and changing as they grew younger. Since Natalie was younger than her mother she reached toddlerhood first, her clothes changing into a pink my little pony t-shirt and a disposable diaper. When her mom finally became three years old she got a my little pony t-shirt and a diaper too, though hers was purple.
Olivia and Natalie took a moment to admired their new diapered selves, the two toddlers smiling at their new attire.
"Wow it's strange to being wearing a diaper again after all these years" Olivia admitted gripping the sides of her crinkly padding and readjusting it.
"It feels good doesn't it?" Natalie replied with a grin.
"It does" she agreed.
"You guys are such babies" Brianna said with a roll of her eyes.
"That right, and now that we are babies you are going to have to take of us" Olivia stated to her oldest daughter, "That means playing with us, feeding us, bathing us and of course changing our diapers" she said with a grin at the last part.
"Easy, I can take care of you two no problem" Brianna said looking smug.
