What Age Is a Toddler?
By First Cubby Editorial · Updated 2026-07-04
A toddler is generally a child between about 1 and 3 years old — from when they start walking (“toddling”) until around their third birthday. After age 3, children are usually called preschoolers.
The stages, roughly
- Baby / infant: 0–1
- Toddler: 1–3
- Preschooler: 3–5
- School age: 5+
The labels blur at the edges — a young 3-year-old and an old toddler look a lot alike — and sources vary by a few months. What matters is your child’s development, not the label.
From toddler to preschool
Around age 3, many families start looking at preschool. See what age preschool starts and your 3-year-old for what comes next.
