I loved this story. At the beginning there was a unique start, with a journalist combining both of his love with writing and diapers. It was a great selling point.
Then we saw how control was soon to be lost with the support of his mother. Again, whilst this was happening, there was a nice steady progession to the story.
However, the last few chapters seem to have come to a standstill. No longer is there an end goal in sight. It seems that this story has now come to the point that no longer is he an adult, and no-one sees him this way. Whether it be family, friends, acquaintances or even strangers. What gets me is the fact he seems to be in "little space" permanently.
There is no mention of his desire to become a renowned journalist, there is no mention of potty training, even though his little cousin is showing signs of this. Wasn't the point of the story to be potty trained with him?
I think some sort of progression is needed in this story. It seems like it is the end, the chapter offered the same scene as someone would put in the final chapter in their book. The only thing missing after this was "and they lived happily ever after" it seems.
I think you may need to start taking the story on a storyline again. Whether to explain the permanent regression or to get back on track with the potty training narrative would be great for your story.
Overall, i do really like your story, i just lose interest when a dead end appears to coming and i would really like this story to remain in my top list for some time.
I don't mean to be nasty, i want this to be treated with the same intention as why i have written this feedback (abiet unsolicited feedback) as constructive criticism.
Hope you keep writing.
