Sense: noun/1
These four terms all refer to young humans but mark different developmental stages. Baby is the broadest informal term, used from birth until about age two or three, but strongly associated with non-walking infants. Infant is the formal, clinical term for a child under one year old — used in medical records and parenting books. Toddler (the entry word) fills the gap between baby/infant and preschooler, referring specifically to children aged roughly one to three who are learning to walk. Preschooler describes children aged three to five, old enough to attend nursery school and walk confidently. Child is the most general term, covering all ages from baby to teenager. For example, a pediatrician might track an infant's growth at six months, watch a toddler's walking development at eighteen months, and assess a preschooler's language skills at age four.

Etymology
The word 'toddler' comes from the verb 'toddle', which describes the short, unsteady steps a young child takes when first learning to walk. The suffix '-er' turns the action into a person who does it. 'Toddle' first appeared in English around the year 1600, probably from Scottish or northern English dialect sources, where it may have been related to the older word 'totter' (to shake or sway). The noun 'toddler' itself was not widely used until the late 19th century, when parenting and child-development literature needed a precise term for children past infancy but not yet ready for nursery school.
