Timmy was the first to be tested. Kathy grabbed a diaper that had building blocks on the front. She undid the tapes of Timmy's diaper and lifted his legs pulling the wet one from underneath him and into the trash. She wiped him down and powdered him. She knew exactly how this diaper was going to react. She unfolded the new diaper and lifted his legs again putting the diaper underneath. She pulled the diaper between his legs and fastened the tapes. Timmy sniffled a bit and felt a familiar tingle that he felt when the world changed. He quickly started to go back in age as the months dwindled from him as he grew smaller into the diaper. He started to cry as he realized he was getting smaller. As he became a year old the diaper changed size to the according fit of his age. The diaper slowly lost it's prints as they minimized. The designs on it changed with his age too reflecting his development. The images changing from building blocks to teddy bears walking. Timmy tried get up but the strap kept him down. Soon enough he would have found himself having problems walking. As the months dwindled he cried harder afraid of what was happening to him. Kathy watched on curious as to what would happen. Timmy was soon 6 months old and his infantile reflexes started to take over. He found himself peeing in his diaper scared of what was happening. Soon his skin started to get redder, he became much smaller as he turned into a month old newborn. The diaper lost its print of the blocks on the front and turned white leaving designs of a stork. Soon enough an umbilical cord grew from his stomach and laid next to him. Kathy watched on for what would happen next.
