Over the next few days, Timmy got used to the new situation. After the many confusing changes, he actually came to like staying the same, even if it meant to be three years old. Now he could enjoy a carefree early childhood with lots of playing, cuddles and bedtime stories from his new mom and dad. He knew that Kathy was safe in his mom's womb, and whenever he missed her he could just put his hands on mommy's growing belly and wait for the baby to move, talk to her through the womb and put his ear on mommy's warm skin and listen intently.
The only thing he had to take care of himself was potty training, and he found that to be quite easy. Whenever he felt the need to pee or poo, he would announce it to mommy or daddy who would drop whatever they were doing and rush him to the bathroom, take off his trousers and training pants (although he could do that himself already!), put him on the toilet and then be overjoyed at any trickle of pee and even the tiniest of turds their little man dropped. When he was playing or concentrating on something else, he sometimes didn't notice his full bladder before it was too late and his training pants got wet, but he quickly learned to take care and such accidents became rarer. After two months, he managed to not use his training pants for two days in a row.
On the morning of the third day, his mommy announced "Timmy, you're a big boy who goes to the toilet, so you can wear big boy pants now. We're very proud of you! Just remember these won't hold any pee, so be careful!". He was very proud, too, and loved his new pants with dinosaur and Spiderman designs which he wore all day now and (almost) always kept dry, only returning to diapers at night when he would still pee without waking up.
Of course, there were difficult moments too, like when in the supermarket he saw a toy or a candy bar he wanted but his mother refused to give it to him for no reason at all. Then he found himself forced to cry bitter tears, scream and roll on the floor, but mostly it didn't do him any good. Also his parents denied him the right to drink nothing but lemonade and insisted on boring water and stupid juice. But those hardships were easily forgotten after a short cool-off period and playing with his toys in his room, or a cuddle session with mommy or daddy he could get just by saying sorry.
