If you are saying something that belongs to the larynx, as in "the larynx's cartilage protects the throat" then you use apostrophe S.
Use 's when indicating possession or contraction (e.g. Sarah's cat, it's sunny) and use s' to show possession for plural nouns (e.g. the students' desks).
peaking out of his mother's pouch or peaking out of his mothers' pouch?
Use an ''s' when you are indicating possession. Use 'ies' when you are indicating plurality.
An 's preceded by an apostrophe ('s) indicates possession or contraction (e.g., John's book, it's raining). An s followed by an apostrophe (s') is used for plural possessives where the noun is already plural (e.g., the girls' toys).
s' is used as an apostrophe for a word that refers to plural form, for example saying The girls' toys. In this instance it refers to the toys of more than one girl. You would also use s' for names ending with an s, such as Tess' toys. 's is used as an apostrophe for a word that refers to singular form, for example saying The girl's toys. This refers to the toys of just one girl. You would also use 's with names such as Tom's toys
