At 18 months your toddler is running (a little wobbly), pointing at everything, and dramatically expanding their vocabulary. The famous "language explosion" is well under way, and imaginative play begins.
18 months old developmental milestones
- Runs with occasional falls
- Points to at least three body parts on request
- Uses around 20 words and understands hundreds
- Pretends to feed a doll or drive a car
- Removes socks and shoes
Care tips for 18 months old
- Trade the bottle for a cup at every meal to protect the new teeth.
- Set up a "yes space" — a room where nothing is off-limits and toddler can roam safely.
- Read every day. Even five minutes of reading has an outsized effect on vocabulary.
- Sing action songs — they build rhythm, memory, and gross motor skills all at once.
This month's checklist
- Attend the 18-month check-up
- Set up a safe "yes space"
- Read together for at least 10 minutes a day
Frequently asked questions
How many words should an 18-month-old say?
Around 20 words is the average, but 5-50 words is a normal range. The bigger question is whether new words are being added every week.
Is screen time OK at 18 months?
Under 1 hour a day of high-quality, co-viewed content. Avoid background TV — it interrupts language development.
When should I worry about speech?
Mention it at the 18-month or 2-year check if your toddler uses fewer than 10 words, does not respond to their name, or has lost words they used to say.
When to call your paediatrician
Most months of babyhood pass without alarm, but a small set of symptoms always deserves urgent review. Contact your paediatrician or the nearest paediatric emergency room straight away for any of the following:
- Fever above 39 °C, or any fever lasting more than 72 hours
- Refusing more than two feeds in a row, or fewer wet nappies than usual
- Breathing that is fast, noisy, or with visible chest tugging
- Persistent vomiting, blood in stool, or a swollen belly
- Any sudden loss of a skill baby had already learned
Where the 18 months old stage fits in
Between one and two, walking becomes running, sounds turn into words, and toddlers begin to test the edges of independence. Language, empathy, and imagination all bloom during this year. Predictable routines, generous naming of feelings, and lots of shared reading power the biggest gains.
Educational content — not a substitute for medical care. Contact your paediatrician urgently for high fever in a young infant, refusing feeds, laboured breathing, persistent vomiting, or any concern that feels wrong to you.
