Katie did not know Lisa still had the ring on while they watched the movie. The two ten year olds ate their snacks and watched the "The Little Mermaid" movie. At first they were simply watching, but soon were starting to giggle and sing along with the songs acting more and more like the kids they were. By the end of the movie, they were happy ten year olds enjoying themselves, and their older selves were a passing thought.
"I'll put in Frozen now, I want to see it." said Lisa, hoping off the couch. She held up her sleep pants since they were slipping down.
"That's a little kids movie." said Katie.
Lisa stuck out her tongue, "Nah so, my sleepover, my movie." She put in the movie and started play. Lisa quickly joined Katie on the couch. In her mind Lisa thought, "So what its a little kids movie, we're little kids now." Not knowing her thoughts were affecting the ring.
As the movie started, their PJ's started to change, they shrank to fit their younger bodies and became more childish. They were now wearing pajama's fitting a 10 year old. By the time Anna's was singing, "Do you want to build a snowman", both Lisa and Katie thoughts were of being sisters. Katie's room changed from a teenagers room to a little girls room with two beds. They started to sing along during, "For the first time in forever." Subconsciously, Lisa's thoughts were gradually making them even younger as they watched. She so wanted Katie to enjoy the movie and if being a little kid would do it, she wanted them to be little. So as the movie progressed, both Katie and Lisa passed through grade school in reverse. At the same time, their Pajama's regressed with them becoming more childish in style the younger they got. Their voices got higher and their bodies got smaller. By the time in the movie where Anna meets her sister in her ice fortress, instead of two 10 year olds watching the movie, Lisa has regressed them both back to 6 year old first graders.
"I like Elsa," said Lisa grabbing more popcorn.
Katie finished her sip of her soda, "Me too"
They went back to watching. But the changes and thoughts from Lisa were not done, and Katie and Lisa went further back. Their pajama's changed even more. They were no longer wearing a top and sleep pants, and now only wore a tee and undies. Baby fat returned with a vengeance. They now had all their baby teeth again. It was a good thing the movie ended when it did, if not Lisa might have advertently returned them back to the womb, but as it was, it was bad enough. Now sitting on the large couch were two little 2 year old toddlers in diapers sucking from baby bottles.
"Bes'd movee evew" said Lisa pulling out her baby bottle.
Katie nodded, "Uh huh, nice mommy wet us wa'dch id".
"Being widdle fun" giggled Lisa. She padded her the front of her diaper. "Dipee fun"
Katie smiled, "Yeah, but we's gots be big kids tomowwow"
"Oh yeah me forgots." said Lisa and looked at the ring that had slipped off her finger and onto the couch. She picked it up. "Make us big kids tomowwow." She looked at Katie. "All dones, wace you to beddy bye." She put the ring back on the couch.
With bottles in hand, both toddlers climbed off the couch and giggled their way back to their room. They climbed into their cribs and pulled up the rails. After bouncing a few times giggling, they finished their bottles and went to sleep. They never noticed the toddler sitting in the chair by the couch sucking on her own baby bottle.
"Me's goes beddy bye's too", she thought after finished her bottle. She climbed off the chair and waddled to the master bedroom. But inside its was another nursery with another crib. She climbed inside and went to sleep.
During the night, all three toddlers were slowly growing older again. The rooms changed from nursery's to little girls rooms filled with toys and stuffed animals. Oddly the only thing that did not change with them were the diapers, which were wet. Lisa was not very specific on how old being a big kid was, in her young mind at the time, kids going to school were big kids. So now sleeping in the two beds were little girls at 5 years old age, ready for kindergarten, but in the third one, she was younger. The little girl in her own room, woke up first.
She yawned, "Best sleep ever, slept like a baby", she giggled. She felt the wetness at her crotch. "And peed like one. Good thing I was wearing a diaper." The diaper was a little tight but still fit. She crawled out of bed and walked to the mirror on the wall. Next to it were tick marks marking growth with numbers and the name Natalie above them. She walked up the tick marks and read them looking at yesterday's date and age. "Great , I'm just turned 4 years old again." Her hand on the happy birthday 4 year old mark. "Lisa only grew me back up to four. I'm younger than them now". She posed in the mirror. "Look at me, little Natalie, only 4 years old and mother of two." Smiling she removed her wet diaper and pulled up a pair of undies from the dresser. Natalie walked to the living room and picked up the ring and took it back to her room. "Well since I'm only four now, let's pway." She giggled and started playing with her toys.
Back with Lisa and Katie, they woke up.
"Best sleepover ever", said Lisa.
"Yep, it was fun being little." said Katie.
"Hmm Katie, we're still in diapers, wet diapers." said Lisa pointing her diaper. "Why didn't they change when we grew back up?"
Kate thought about it for a second, "Maybe cause we wet them, and ring make it so we didn't wet our beds."
"Oh, that make sense." said Lisa. She did not like the feel of the wet diaper and removed it.
Both girls got dressed in undies and heard giggling coming from their mother's room. They looked in and saw a little girl playing with toys.
Katie looked at Lisa, "Mommy look littler than us."
Lisa smiled, "Cause she is, she only four now". She held up four fingers. "I made her only four, we in charge now."
"Cool," smiled Katie.
"Let's surprise her." said Lisa.
"Okay." replied Katie.
Both girls walked in and shouted together
"Hi Mommy" said both girls at the same time.
Natalie looked up at her girls, "Hi, I had fun last night."
Katie looked at her young mother, "You like being a baby."
"A little, makes the whole world seem new again." said Natalie.
Lisa grinned, "So you wanta be a little baby again."
Natalie smiled, "Maybe, but then you two would have to take care of me. But I haven't decided yet, since it's my turn with the ring."
Lisa looked at Katie and whispered, "Maybe we can convince her to be a little baby so we can be the mommy's."
Katie whispered back, "How?"
"Make her want to be littler, she have ring on, make her think about being little and ring will make her littler and littler till she's just a little bitty baby again." replied Lisa in a whisper.
"Oh good plan." whispered Katie.
Natalie tilted her head, "What you girls whispering about?"
"Nothing mommy, just deciding on what to play with you." said Lisa.
"Oh, okay." said Natalie.
"Come Katie, let's play with mommy." grinned Lisa, devilishly.
