# At what age does a child develop long-term memory?

Publisher: Pinnacle Blooms Network / Bharath Healthcare Laboratories Private Limited

Long-term memory builds gradually across the toddler years, not at one fixed age. By 12 months babies recognise familiar faces and routines; by 18–24 months they recall events from days ago; and by 2–3 years they hold memories over weeks and use the past to guide what they do. Wide variation is normal.

*When your toddler suddenly remembers where you hid the biscuits last week, that's long-term memory blossoming — and it starts earlier than most parents imagine.*

## In short
There is no single switch-on age for long-term memory — it builds gradually across the toddler years (roughly 12 to 36 months). By around 12 months, babies recognise familiar faces and routines; by 18–24 months, toddlers recall events from days earlier; and by age 2–3, they begin holding memories over weeks and using past experiences to guide what they do next. This is normal, expected development — not something a young child either "has" or "lacks".

## The science
Long-term memory in toddlers shows up in everyday ways long before children can talk about it:
- **12–18 months** — recognising a grandparent after time apart, finding a hidden toy, anticipating a familiar routine like bath-time.
- **18–24 months** — imitating an action seen days ago (called *deferred imitation*), remembering where favourite objects are kept.
- **24–36 months** — recalling past outings, naming people not present, and learning new words that stay learned.

Memory grows hand-in-hand with language, attention and play, so the richest sign of healthy memory is a child who is curious, connecting and building on what they already know.

## When to check in
Memory varies widely between healthy children, so isolated forgetfulness is rarely a worry. Do mention it at a developmental check if, by age 2–3, your child does not recognise close family, seems to lose words or skills they once had, or shows little interest in familiar games and routines — especially alongside delays in speech or play.

## The Pinnacle way
At Pinnacle Blooms Network, a clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an online read. Explore how [long-term memory](/long-term-memory) develops, and how [occupational therapy](https://www.pinnacleblooms.org/best-occupational-therapy-center-india-proven-improvement-rate) gently strengthens attention and recall through play.
