What is a child? The UN Convention on the Rights of the Child defines a child as everyone under 18 unless, under the law applicable to the child, majority is attained earlier (Office of the High Commissioner for Human Rights, 1989). The UK has ratified this convention.
Infant - various definitions. Toddler - older. Explanation: In medicine, an infant is a child under 12 months (at least in the UK). However, in UK schools, the 'infant years' are (or used to be - the system is different now from when I was at school!) the period from ages 4 to 7. The child would then progress to junior school (often within the same school) at age 7. 'Toddler', as far as I know, has no definition in medicine and is colloquially used of a child who is big enough to walk but is still considered a baby - 'toddling' is the kind of unsteady walking associated with young children.
