Standardisation of accepted terms

At ACESL, we believe that defining standard terms in the baby carrying industry is important, to encourage clarity and facilitate straightforward communication between professionals and the public. We are creating this glossary of terms to both explore the current meaning of each term as it has grown organically, and also to provide a point of reference for all, helping to define the terms going forward.

It is important to use straightforward, easily accessible language which respects the origin and background of a term, including making sure any word or name translated to English is done accurately and respectfully.

We have included obsolete terms in the glossary, which must include phrases and definitions which have formed a part of the baby carrying industry in the past, to better explain why a word is no longer considered appropriate. Brand names will not be included, although there are many that bear resemblance to general terms.

We welcome all additions to this glossary of terms, to further refine and sharpen each definition.
