Babies for a Day

It lands on a one
"OH NO!!" Karyn "we're going to become babies!"
"It was a gamble, after all, but just for a day at least" Jon
Both of them were shrinking at a fast pace;
15, 14
13: Jon's muscles disappeared, his clothes and room changing to match his current age. Karyn's breasts became nonexistent in about a minute, her shirt and skirt merged becoming a dress also matching her current age.
12: Jon's room is a kid's room
11, 10, 9, 8, 7, 6
5: Both of their underwear becomes training pants, Karyn's dress becomes shorter. Jon's bed becomes low to the ground, and has a plastic covering.
4: Their training pants become puffer.
3: Their training pants become pull-up, Jon's pants disappear and Karyn's dress becomes a shirt, exposing both of their pull-ups to each other.
2: Their pull-ups become characterized diapers (Karyn: Minnie Mouse, Jon: Elmo), Jon's bed is replaced by a crib and changing table
1: Their characterized diapers become plan white diapers.
Jon in his baby body, gave a self survey of himself; can only stand, can't walk, can't talk, short hair, no teeth, only wearing a baby blue T-shirt and a diaper, the diaper felt like thick plastic underwear.
