24-Month-Old Milestones: Running, 200+ Words, Autism Screening

• By 24 months most toddlers run, climb onto furniture, walk up and down stairs holding a rail, kick a ball, and attempt to jump with both feet off the floor.
• Language jumps fast around now: roughly 200 words (counted across all the languages your child hears) and the first 2-word phrases like 'more milk' or 'Mama go'.
• Parallel play (playing alongside, not yet with, other children) and the 'terrible twos' tantrums are normal and healthy, not bad behaviour.
• The IAP 24-month visit includes M-CHAT-R/F autism screening, a check that all earlier vaccines are complete, and a catch-up typhoid conjugate dose if needed.
• Red flags worth raising early: fewer than 50 words, no 2-word phrases, not walking or running, loss of skills already gained, or no eye contact and no pretend play.
• If something feels off, act on it. Early identification before age 3 and prompt intervention give the best long-term outcomes.

By 24 months most toddlers move with real confidence. A typical 2-year-old runs (even if a little stiffly), climbs onto chairs and the sofa, walks up and down stairs while holding the rail, kicks a ball, and is starting to jump with both feet leaving the floor for a moment.

What to expect by 24 months (per WHO motor milestone data and AAP/IAP guidance): runs; kicks a ball; climbs onto furniture; walks up stairs holding the rail; walks down stairs holding the rail. Jumping in place with both feet usually appears between 22 and 30 months, so around half of 2-year-olds are doing it. Standing on one foot and throwing a ball overhand typically come a bit later, closer to 28 to 36 months, and are not yet expected now.

These are average ranges, and Indian toddlers sometimes practise different skills depending on where they live. A child in a high-rise flat with no garden may climb stairs later simply because there are fewer chances to practise, not because anything is wrong. That is environment, not delay. What matters is steady forward progress.

To support movement at this age, aim for the WHO recommendation of at least 180 minutes of physical activity spread through the day, including active play. Useful options at home:

Toddlers learn through repetition, so the same simple games on most days do more good than expensive equipment used occasionally.

Fine motor skills are growing quickly too. At 24 months most toddlers stack a small tower of blocks, scribble with a crayon, turn the pages of a board book (sometimes several at once), and feed themselves with a spoon, with plenty of spills.

What to expect by 24 months: stacks roughly 4 to 6 blocks; turns book pages; uses a spoon to self-feed; drinks from an open cup; scribbles spontaneously; begins to imitate a vertical line; uses a precise pincer grasp for small objects; and helps pull off shoes, socks or pants. Many also start having a turn at toothbrushing with you finishing the job.

Hand dominance is usually not fixed yet. Most toddlers use both hands fairly equally until 3 to 4 years. A very strong preference for one hand before age 2, where the other hand is barely used, can occasionally signal weakness on one side and is worth a paediatric check.

Good ways to build these skills (small objects under 2 cm are a choking hazard, so always supervise):

Language often takes off dramatically between 18 and 24 months, going from perhaps 20 to 50 words to around 200 words. The big leap is the move from single words to 2-word and 3-word combinations such as 'more milk', 'Mama go' or 'big dog'. That shift matters because it shows your child is starting to use grammar and to put ideas together.

What to expect by 24 months: about 200 words (experts cite a wide range of roughly 100 to 300); 2-word phrases; names familiar objects (cup, spoon, ball, dog); points to several body parts; follows simple two-step instructions ('pick up the ball and give it to Mama'); and imitates words and sounds. Understanding runs ahead of speaking, so your toddler grasps far more than they can yet say. For more on this stage, see our deep dive on the 18-to-24-month language explosion.

Bilingual and multilingual homes are the norm across India, and this is good for your child. Count words across all the languages they hear: a toddler with 100 Hindi words and 100 English words has met the 200-word mark. Mixing languages in one sentence (code-switching) is completely normal and is not a sign of confusion or delay. Our guide on raising a bilingual child goes into this in more detail.

Simple, daily things help language most: reading together, narrating what you are doing, singing rhymes, naming objects, and expanding on what your child says ('cat' becomes 'yes, a big brown cat'). Background TV and heavy screen use reduce the back-and-forth talk that drives language, so keep screens off during play and meals.

Socially, 2-year-olds play alongside other children rather than truly with them. This is called parallel play; genuine cooperative play comes closer to 3 to 4 years. You will also see more pretend play, such as feeding a doll or 'talking' on a toy phone, and clear preferences for favourite people, foods and toys.

What to expect by 24 months: shows defiance and asserts independence; engages in parallel play; imitates household activities like sweeping or cooking; begins to use 'me', 'you' and 'mine'; recognises themselves in a mirror; shows affection openly; and has tantrums when frustrated. Separation anxiety, which often peaks around 18 months, is usually easing now. This builds on the social milestones of 12 to 18 months.

The 'terrible twos' label is unfair. Tantrums reflect a child who is discovering they are a separate person with their own wishes but who does not yet have the brain maturity to manage frustration. Crying, screaming and flopping on the floor are normal responses to big feelings, not bad behaviour or bad parenting. They peak around 18 to 30 months and ease as emotional regulation matures over ages 3 to 5. What helps:

Time-outs are not generally recommended for under-3s; a calm 'time-in' beside you usually works better. Our toddler tantrum toolkit has more strategies.

Indian joint families give toddlers several loving caregivers, which is enriching, but it helps to agree as a family on a few non-negotiables, especially safety rules around the stove, balcony, choking foods and car seats. Stay consistent on those, and allow flexibility on minor things like an occasional treat or a slightly later bedtime at grandma's.

The Modified Checklist for Autism in Toddlers, Revised, with Follow-Up (M-CHAT-R/F) is a validated screening questionnaire for autism spectrum disorder (ASD) in toddlers aged 16 to 30 months. Both the American Academy of Pediatrics (AAP) and the Indian Academy of Pediatrics (IAP) recommend it at the 18-month and 24-month visits. Screening is not a diagnosis; it flags children who would benefit from a closer look.

Autism is a neurodevelopmental difference in social communication and in patterns of behaviour and interests. Estimates suggest it affects roughly 1 to 2 percent of children, similar to global figures, though in India many children are identified later than ideal because of limited awareness and access. Early signs can include reduced eye contact, not responding to their name, limited pointing or gestures, little or no pretend play, and repetitive behaviours.

The M-CHAT-R/F is a 20-question form that parents complete in about 5 to 10 minutes. It asks things like whether your child looks at you when you call their name, points to ask for things, and plays pretend. Scores fall into low risk (0 to 2), medium risk (3 to 7) or high risk (8 to 20):

The questionnaire is free, can be self-administered at mchatscreen.com, and most paediatricians use it at the recommended visits. If yours has not screened your 24-month-old, you can ask for it. Formal evaluation by a developmental paediatrician or child psychiatrist may use tools like the ADOS-2. In India this is offered free or at low cost at government tertiary centres such as AIIMS, NIMHANS Bengaluru and PGIMER, and at varying prices in the private sector.

If screening is concerning, follow through with referral promptly. NGOs such as Action for Autism (Delhi) and Communication DEALL (Bengaluru), and government services through District Disability Rehabilitation Centres, provide assessment and support. Children identified before age 3 and started on appropriate therapy (speech, occupational and behavioural) generally do substantially better than those identified later.

The 24-month visit is a good checkpoint to make sure every earlier vaccine is complete and to give any catch-up doses. Always bring your vaccination card.

Typhoid conjugate vaccine (TCV): typhoid is endemic in India and spreads through contaminated food and water, so the IAP recommends TCV for all Indian children. A single dose is given around 9 to 12 months, and is now preferred over the older Vi polysaccharide vaccine. If TCV was missed earlier, it can be given now. It is free under the Universal Immunisation Programme (UIP) in covered states and around Rs 1,500 to 2,500 privately.

Other vaccines to confirm are complete: MMR (measles, mumps, rubella) both doses; the DTaP-IPV booster usually due at 15 to 18 months; the Hib booster; hepatitis A (2 doses); varicella (chickenpox, 2 doses); pneumococcal conjugate (PCV); and the annual flu vaccine each year from 6 months. In Japanese encephalitis endemic areas, JE doses are given per UIP.

If cost is a concern, government UIP centres provide the core schedule free, and many states now include Hib, PCV and rotavirus in UIP. Keep records in your physical card and, if you use it, the digital ABHA/CoWIN record; most schools ask for a complete vaccination history at admission.

For the full picture from birth onwards, see the IAP newborn vaccine schedule and our broader baby vaccination schedule.

The IAP and AAP recommend a first dental visit by the time the first tooth appears (around 6 months) or by the first birthday at the latest, then roughly 6-monthly check-ups. By 24 months your child likely has most of their 20 baby teeth, with the full set usually complete by about 30 months. A private paediatric dental visit costs roughly Rs 500 to 2,500, and government dental hospitals are free or subsidised.

Brush twice a day with a soft toddler brush and a rice-grain smear of fluoride toothpaste (around 1000 ppm). You should do the brushing; toddlers do not have the coordination to clean teeth properly until 6 to 8 years, though letting them 'have a turn' builds the habit. Avoid bottles or sippy cups of milk or juice in bed, which cause front-tooth decay, and keep sweets to mealtimes rather than between-meal snacks.

On food, most 2-year-olds eat a modified version of the family diet: three meals plus two snacks, roughly 1,000 to 1,400 kcal a day depending on size and activity. Offer variety across grains (rice, roti, ragi), dals and pulses, paneer, curd, eggs, vegetables and cut fruit. Iron matters especially, because iron deficiency anaemia is very common in young Indian children. Pair iron-rich foods with vitamin-C foods like tomato or citrus for better absorption, and keep tea and coffee away from meals.

Keep milk to about 400 to 600 ml a day, since too much milk blunts appetite and crowds out iron. Limit juice to about 120 ml a day, diluted, and make water the main between-meal drink. Continue to avoid whole nuts, whole grapes, raw carrot and popcorn (choking hazards under 3) by grinding or cutting them small.

Picky eating is extremely common now, with food jags and sudden refusals. Keep offering rejected foods without pressure; children may need 10 to 15 exposures to accept something new. Avoid screens at meals and avoid making a separate dish every time. For how solids progress into this stage, see our guide to first foods and weaning.

At 24 months most toddlers need around 11 to 14 hours of sleep in total, including one afternoon nap of 1 to 2 hours and 10 to 12 hours overnight. The shift from two naps to one usually happens around 15 to 18 months; some children drop the nap by 3 to 4 years, others keep it longer. Our guide on nap transitions covers this in detail.

A sleep wobble around 18 to 24 months is common, driven by all the developmental change happening at once, and usually settles within a few weeks. Keep a consistent bedtime and a calm routine (bath, story, lights out), avoid screens for an hour before bed, and respond to night wakings briefly and quietly. If sleep keeps unravelling, our piece on baby and toddler sleep regressions may help.

Toilet-training readiness typically appears somewhere between 18 and 30 months, with wide variation. Wait for several readiness signs rather than a fixed date; pushing too early tends to lengthen training and can cause stool withholding. Look for:

Approaches in India vary, from early elimination communication to child-led training around 2 to 3 years. The current paediatric recommendation is child-led training once readiness signs are present. Daytime training usually takes 3 to 12 months, and night dryness comes later (commonly 3 to 5 years). Our India toilet-training guide walks through the steps.

Independence is blossoming: attempts at self-feeding, drinking from a cup, helping with handwashing and dressing, and following simple instructions. Encourage these even when they are slow and messy, offer choices within limits, and praise effort. At the same time keep close safety supervision; 2-year-olds cannot yet judge danger around stairs, water, roads or hot objects.

AAP and IAP screen-time guidance: none for under-18-month-olds except video calls; only small amounts of high-quality content co-viewed with a parent at 18 to 24 months; and up to about 1 hour a day of high-quality content for 2 to 5 year olds. Many Indian homes exceed this, often because the TV runs continuously. The main downside of excess screen time is less talking, less active play and disrupted sleep. Our India screen-time guidelines explain how to set realistic limits.

Quality matters as much as quantity. Educational programming watched together, where you talk about what is happening, is very different from passive background viewing or autoplay feeds. Avoid screens during meals and before bed, and try not to rely on a screen to stop tantrums, which builds dependence.

Play is how toddlers learn. Offer a mix of physical play, building and sorting, pretend play, art, music and daily reading, which is one of the most powerful things you can do for later language and learning. Plenty of free, unstructured play matters more than any single toy.

Useful, low-cost Indian play options include chunky wooden blocks, shape sorters, stacking rings, simple knob puzzles, play dough, crayons, board books (Pratham, Tulika and Karadi Tales offer affordable titles in many Indian languages), a toy kitchen or doctor set, and balls for outdoors. Keep the toy count modest and rotate toys to keep them interesting.

Above all, warm, responsive interaction with you is the single biggest driver of development, more than any toy or programme. Everyday moments such as cooking together, walking, household chores your toddler can help with and chatting about photos all give rich input. Try to keep your own phone down during play; toddlers notice.

Most toddlers develop within a normal range with plenty of individual variation. But some signs at 24 months are worth raising with your paediatrician promptly, because early identification and intervention substantially improve outcomes. The IAP recommends developmental surveillance at every visit, formal screening at set ages, and autism-specific screening at 18 and 24 months.

Talk to your paediatrician at (or before) the 24-month visit if you notice any of these:

A loss of skills your child previously had (motor, language or social) is especially important and should always be checked. Your paediatrician may use screening tools such as M-CHAT-R/F or ASQ-3 and, if needed, refer to a developmental paediatrician, speech-language pathologist, occupational therapist, physiotherapist, or an ENT specialist with audiology for hearing concerns.

Indian early-intervention pathways include government centres such as AIIMS Delhi, NIMHANS Bengaluru, CMC Vellore and PGIMER Chandigarh, and District Disability Rehabilitation Centres and Composite Regional Centres that offer free or subsidised assessment and therapy. The Rights of Persons with Disabilities Act 2016 recognises autism and several developmental conditions and provides specific protections and benefits. If you have a concern, act on it rather than 'wait and watch'. Early support works.
