What's UP with Nickelodeon's Diaper Fetish?

1: A number of episodes have characters being

Dressed like Babies, or Turned into Babies.

2: An episode has Squidward being turned into a

big Baby, which disturbs some for making light

of head trauma and baby perverts

3: The Loud House makes Smelly Diaper Jokes around

13-18 times/week, and put Lincoln and Lisa in Diapers.

4: Alvin in the recent series goes on a skateboard

into the schoolgrounds in a shirt and diaper,

why, I don't know.

5: And now Jace Norman is wearing a Diaper, albeit on top of his normal pants. WHY?
