YOUR QUESTION. A CLEARER NEXT STEP.
At what age does a child develop long-term memory?
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.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Mention it at a developmental check if, by 2–3 years, your child does not recognise close family, loses words or skills once learned, or shows little interest in familiar games — especially with speech or play delays.
In everyday life
Play 'do you remember?' — talk about yesterday's outing or last week's visitor. Naming past events together strengthens recall and language at the same time.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
Can babies remember things long-term?
Yes — even by around 12 months, babies recognise familiar faces and routines and can find a hidden toy. Long-term memory grows steadily through the toddler years rather than appearing all at once.
Why doesn't my toddler remember some things?
Memory varies a great deal between healthy toddlers, and occasional forgetfulness is completely normal. Curiosity, connecting with family and building on what they know are the best signs of healthy memory.
When should I worry about my child's memory?
Raise it at a developmental check if, by age 2–3, your child does not recognise close family, loses words or skills once learned, or shows little interest in familiar games — especially alongside speech or play delays.
