Terminology
The terminology relating to blanket sleepers can be confusing, and inconsistent between different speakers.
The terms sleeper and blanket sleeper are sometimes used interchangeably. Alternatively, a distinction may be made between the lighter-weight (footed, one-piece) sleepers worn by infants in warmer weather, and the heavier blanket sleepers worn by both infants and older children, primarily in colder weather. (In the loosest usage, sleeper by itself can mean any infant sleeping garment, regardless of form or features.) Similarly, some people consider a blanket sleeper to be one-piece by definition, whereas a sleeper could be made either in one piece, or in two pieces meeting at the waist.
When blanket is omitted, either the singular form sleeper or the plural form sleepers may be used to refer to a single garment. When blanket is included, however, a single garment is usually referred to using the singular form.
The terms (blanket) sleeper and footed pajamas may be used interchangeably. (This reflects the North American practice of referring to nearly any sleeping garment as pajamas, as blanket sleepers bear little resemblance to the jacket and trouser combination, originating in India, that the term pajamas originally referred to.) Alternatively, sleeper may instead be used more narrowly than footed pajamas, to exclude footed sleeping garments that are lighter-weight and/or two-piece, such as footed "ski" style pajamas.
Also, while many people consider built-in feet to be part of the definition of sleeper, garments otherwise meeting the definition but lacking feet are sometimes marketed as footless blanket sleepers.
The term grow sleeper is sometimes used to refer to a two-piece footed sleeping garment with features designed to compensate for growth in the wearer, such as turn-back cuffs, or a double row of snap fasteners at the waist.
Other terms that are used more-or-less interchangeably with blanket sleeper include:
- footed sleeper

- feeted/feety/footy/footsie/feetsie/feet pajamas
