As Tommy got further away, Lizzy started to panic so she did the first thing that came to her mind.
"Tommy!", Lizzy yelled as loud as she could. Just then, Jason proceeded to turn around only to find that Jason was heading towards the stairs.
"Tommy, where are you going?" Jason asked him.
"I-I just wanted to go upstairs and play," Tommy said nervously trying to think of an excuse for his escape.
"You know you can't go upstairs. Come help me change your sister's diaper and then you can play," Jason replied. Tommy had no choice but to accompany Jason to the living room where they would change Lizzy's diaper.
Lizzy was very happy that she prevented Tommy's plan, though her happiness was soon dashed when she found out that Jason started laying her down on a changing mat and started taking her clothes off.
While Jason was changing Lizzy, he asked Tommy to pass him something from the diaper bag. Whether it's baby wipes or baby powder. And while he did what Jason asked him to do, Tommy stared at his sister with an angry look for having prevented him from going back to normal.
By the time Lizzy's change was almost over, Jason asked Tommy to hand him a diaper and one of Lizzie's onesies. Searching in the diaper bag, Tommy found what Jason asked for but noticed that these were designed for babies and not for toddlers. As a way to get back at Lizzy, Tommy gave them to Jason and he ended up putting them on Lizzy.
After Jason dressed her, Lizzy couldn't help but feel that something was wrong. For some strange reason, everything looked a little bigger and her body looked smaller and chubby. And for some reason, every time she tried to stand up, she always ended up falling after taking a few small steps.
"Aww, don't worry Lizzie. I'm sure you'll learn to walk soon. In the meantime, let's put you in your baby walker", Jason told her before he picked her up.
"Goo Goo? (My baby walker?)", Lizzie said only to find out that she could no longer speak. It was in that instant that she finally knew what was happening: She had become a baby. Soon, Lizzie watched as Jason placed her into a baby walker perfectly sized for her. It was covered in plastic toys and its seat was just wide enough that Lizzie couldn’t get enough of a stable grip on the ground to stand up.
The only good thing about all this is that Tommy, instead of trying to escape again, stayed watching TV with Jason and his friends in the living room. Maybe she could take this opportunity and try to sneak out. But first she had to get out of this baby walker.
