What does fussiness mean?
Fussiness is the quality of showing excessive or unnecessary concern over small details, particularly regarding food, clothing, arrangements, or standards of correctness. A fussy person is hard to please and quick to object to trivial imperfections, and the trait often carries mildly critical connotations, suggesting pettiness rather than admirable precision. The word also has a well-established second life in childcare and medicine, where infant fussiness refers to periods of fretful, hard-to-soothe crying and irritability. Derived from the older word fuss, which entered English in the seventeenth century, fussiness names a disposition many people recognize instantly, whether in a picky eater, a perfectionist colleague, or a colicky baby. Its usefulness lies in capturing, in a single term, both the temperament that magnifies small annoyances and the visible behavior that results from it, making it equally at home in casual conversation and professional writing about behavior and development.
The quality of being excessively concerned with small details or trivial matters; a tendency to be hard to please or easily upset over minor things.
"Her fussiness about hotel rooms made traveling together exhausting."
Often used pejoratively for adults, but descriptively and without judgment in discussions of infants and toddlers.
Fretful irritability or restlessness, especially in a baby or young child.
"Teething explained the baby's unusual fussiness this week."
Common in pediatric and parenting literature, where 'fussiness' is treated as an observable symptom rather than a character trait.
Rarely used in the plural; as an abstract quality noun, fussiness is almost always singular, and multiple instances are usually expressed as 'instances of fussiness' or rephrased.
"Different kinds of fussinesses emerged as the toddlers grew older — over food, clothes, and bedtime routines."
Fussy babies and fussy eaters made 'fussiness' a household word — yet the word 'fuss' itself has no clear origin, appearing suddenly in English in the 1600s with no one quite sure where it came from.

Etymology of fussiness
Fussiness derives from fuss, a term that appeared in English in the early seventeenth century meaning a needless bustle or commotion. The ultimate origin of fuss itself is uncertain; it may be echoic of the sound of busy agitation, possibly influenced by Scandinavian words such as Danish fus, meaning brisk or fidgety. From fuss came the adjective fussy and, in turn, the abstract noun fussiness, following the common English pattern of forming quality nouns from adjectives.
