* Poupon: This is the most common term for a baby doll, especially a small, plastic one.
* Poupée: This is the more formal French term for "doll," but it's less common in Cajun French.
* Poupette: This is a more affectionate term for "doll," similar to "little doll."
The best translation will depend on the specific situation and the kind of doll you're referring to.
For example, if you're talking about a porcelain doll, you might use "poupée de porcelaine." Or, if you're talking about a toy doll that's small and cute, you could say "un petit poupon."
