tot
Word family
Synonym discussion
Sense: noun/1
All four words refer to young humans, but they differ in age range and formality. 'Child' is the broadest term, covering anyone from baby to teenager, and is neutral in register. 'Toddler' is more specific — it describes a child aged roughly one to three who is learning to walk, so it overlaps closely with 'tot' but emphasises the walking stage rather than the small size. 'Kid' is informal and can cover the same broad age range as 'child', from early childhood into the teenage years; it lacks the affectionate softness of 'tot'. 'Infant' is clinical and refers to a baby in the first year of life, often in medical or legal contexts. For example, you would call a two-year-old a 'tot' affectionately at the park, but a doctor would refer to the same child as a 'toddler' or simply a 'child'.

Etymology
The origin of 'tot' is uncertain. It first appeared in English around the early 1700s meaning a small child, possibly from a dialect word for something small or round. By the 1800s, 'tot' had also come to mean a small amount of drink — perhaps from the idea of a small measure being 'totted up' (added up) or simply an extension of the 'small' sense. The verb meaning 'to add together' appeared in the 1800s as a shortening of 'total'.
