'babydom' originates from English, specifically from the word 'baby' with the suffix '-dom', where 'baby' meant 'infant' and the suffix '-dom' meant 'state or condition'.

'-dom' comes from Old English 'dōm' meaning 'judgment, condition'; in Modern English it combined with 'baby' to form 'babydom'.

Initially, it meant 'the state or condition of being an infant', and over time it has retained this basic meaning as 'babyhood' or 'infancy'.
