- Fridge Horror: When you re-read the books when you're older you realise just how bad the situations a lot of the characters are in are.
- Mary Sue: A lot of her characters turn out like this.
- Nightmare Fuel: The graphic suicide scene in Dustbin Baby
- Periphery Demographic
- Toy Ship: Most of Wilson's books have this in some form. With the exception of Kiss, Dustbin Baby, Love Lessons and the Girls series, all of her protagonists from Tracy Beaker onwards are under 13 years old.
- What Do You Mean, It's for Kids?: Take a Good Look is about a partially sighted girl who decides to go out shopping alone even though she's not allowed, and is caught up in an armed robbery. It faced criticism when it came out for being aimed at 6 to 9-year-olds despite the disturbing descriptions of the heroine being threatened and violently attacked by people she can't see. This is probably the reason it isn't in print any more.
