Editing Blanket sleeper (section)

== 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 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:
* ''footies'' or ''feeties''
* ''footed sleeper''
* ''footed pajamas'' (variants include foot/footy/footed/footsie/feet/feety/feeted/feetsie and may use colloquial terms for pajamas such as pjs or jammies)
* ''pajamas with (the) feet (in/on them)''
* ''padded feet pajamas''
* ''bunny (feet) pajamas'' or ''bunny suit''
* ''one-piece pajamas''
* ''zip-up pajamas''
* ''pajama blanket''
* ''sleeper/sleeping suit''
* ''sleeper blanket''
* ''sherpa sleeper''
* ''walking blanket''
* ''walking sleeper''
* ''sleeper walker''
* ''oversleeper'' (used in advertisements by [[J. C. Penney]])
* ''nighties''
* ''[[onesie (jumpsuit)|onesie]]''
* ''potato mashers''{{citation needed|date=July 2017}}
* ''dormer'' (older girls' and women's sizes only)

Also, a number of commercial brand names have been adopted as [[genericized trademark]]s.  The best known of these is ''Dr. Dentons'', but others used include "Big Feet", ''Trundle Bundle'' (common usage on the Southside of Chicago), and ''Jama-Blanket''.

Formerly used, obsolete terms include:
* ''night drawers''
* ''sleeping drawers''
* ''sleeping garment''   (used in advertisements by Doctor Denton Sleeping Mills)
* ''coverlet sleeper''
* ''pajunion'' (used in advertisements by Brighton-Carlsbad)

In [[British English]], the term with a meaning closest to that of ''blanket sleeper'' is ''sleepsuit'', but it is also known as a ''romper suit''.

Infants' garments similar to blanket sleepers, but with the bottom portion constructed like a bag, without separate leg enclosures, are usually not considered ''sleepers'', but rather are referred to by other terms such as ''baby sleep bag'', ''bunting'', ''[[sleeping bag (infant)|sleeping bag]]'', ''go go bag'', ''sleep sack'', or ''grow bag''.

Infants' garments similar to blanket sleepers, but designed for use as outerwear rather than sleepwear (and usually featuring hoods and hand covers), are referred to by other terms such as ''[[pram suit]]'', ''[[snowsuit]]'', or ''carriage suit''. Some such garments are designed for dual use as both sleepwear and playwear, these are sometimes known as ''sleep 'n' play'' suits.
