What do we call children of different ages?
👶Newborn (baby): 0–3 months.
👶Infant: this term kind of means the same thing as baby, while ‘infant’ is a more formal term. It's something you would read on a medical text or research paper, but it means the same thing as baby.
🧒🏼Baby: this term is used to refer to a little one from birth up until the baby can walk.
👦Toddler: a baby turns into a toddler when they can ‘toddle', i.e. walk shakily. This usually happens around 1 year, but may occur earlier or later, depending on development.
🧒🏼Child: this is the oldest of all the terms in the question.
👦Legally, in many countries a child is anyone under the age of 18.
However, in common usage most people distinguish between a baby, child, preteen, and teenager.
👧🏼Ages 11–12 are preteens or adolescents.
🧑Ages 13–19 are teenagers.
