So fussing is making an unnecessary bother about something which really isn’t important: “Have you got enough layers on, dear?” “Oh, don’t FUSS mother”
It concerns me that the US parlance for a crying baby is that se is “fussy” or “fussing”. If a child is hungry, uncomfortable, tired, frightened, thirsty, cold, bored, or any of the other challenges which a baby does not have the physical resources to overcome alone, what is se supposed to do to avoid having hir emotions branded with the same brush-off as a suburban lady with too many antimacassars? Wait patiently for someone to notice se needs help?
Is it silly to concern oneself with definitions, or do the words we use to talk about children reveal what we really think of them?
