When to worry about speech delay in your toddler
3 November 2026 · 6 minutes
At dinner, your toddler reaches towards the water tumbler and makes a sound, while you try to work out what they need. A grandparent reminds you that their father spoke late too, but you're still wondering when to worry about speech delay. We don't want you to panic over a milestone chart, or put aside a concern that keeps returning. Looking at words, understanding, gestures and hearing together helps us decide what needs attention and what support might be useful.
When to worry about speech delay in a toddler?
Speak with your paediatrician if your child's communication seems behind expected milestones, progress has stalled, or you're concerned about their understanding. First meaningful words commonly appear around 12 months, and by about 2 years, children generally use around 50 words and begin joining two words, such as “more milk” or “amma come”. These are useful reference points rather than a test your child passes or fails on their birthday.
A word doesn't have to sound perfect to count: a consistent sound used meaningfully for the same person or object can be an early word. We also look at pointing, showing you things and understanding familiar instructions, rather than counting spoken words alone. If you're deciding when to worry about speech delay, bring examples from ordinary routines so your paediatrician can consider the whole picture.
What are the warning signs of speech delay by age?
Very little babbling or few gestures around the first birthday, no meaningful words by about 16 months, and no spontaneous two word phrases by 2 years are reasons to seek review. At around 12 months, also mention limited pointing, showing or response to sounds. These signs don't identify a diagnosis by themselves, but they do mean that waiting for a much later birthday isn't the best next step.
Between 18 months and 2 years, difficulty understanding familiar everyday instructions deserves attention even if your child can repeat songs or name colours. Beyond 2 years, a vocabulary that isn't growing or speech that remains very difficult to understand also warrants discussion. You don't need to tick every warning sign before asking for help, and your observations matter even when your child behaves differently at playschool.
What if my toddler stops saying words they used to say?
Losing words or other communication skills at any age needs prompt medical review, rather than a period of watching at home. A child choosing not to say a word one afternoon is different from a clear loss of words they previously used regularly and meaningfully. Tell your paediatrician when you noticed the change, which skills have reduced, and whether there are changes in play, movement or interaction too.
If the loss is sudden and comes with seizures or reduced responsiveness, seek urgent medical care immediately at the nearest emergency department. Don't wait for a speech therapy appointment or an online reply in that situation. If your child is otherwise well but has clearly lost skills, contact your paediatrician promptly and explain the loss specifically, because an assessment of speech alone cannot establish why it has happened.
Why does my child need a hearing test for speech delay?
A hearing check is an early priority because children need reliable access to speech sounds to learn spoken language. Turning towards a mixer or television doesn't tell us whether your child hears all the sounds needed to distinguish words. Hearing differences can be subtle, and middle ear fluid can sometimes affect hearing, so apparent responses to loud household sounds shouldn't be used to rule out a problem.
Ask your paediatrician about an age appropriate hearing assessment with an audiologist, even if your child passed their newborn hearing screen. Hearing can change after that screen, and a toddler may not be able to explain what they aren't hearing clearly. A hearing assessment and a speech and language assessment can be arranged alongside each other, so checking hearing doesn't have to mean postponing all other support.
Does speaking Tamil and English at home cause speech delay?
Growing up with Tamil and English does not cause speech delay, and you don't need to give up the language your family uses most comfortably. A bilingual child's words may be spread across both languages, so counting only English can give an incomplete picture. Tell the therapist what your child says and understands with you, grandparents and playschool staff, including words they use in only one setting.
When relatives say “his father also spoke late”, they're often trying to reassure you, but family history cannot tell us what your child needs now. A late talker may make progress with time, while another child may need support with understanding as well as talking. Keep speaking naturally in your familiar languages, and bring your concerns for review rather than treating a relative's experience as a reason to wait.
Is speech delay a sign of autism?
Speech delay can occur in autistic children, but speech delay and autism aren't the same thing. Some children with delayed speech are not autistic, and some autistic children develop spoken words within expected timelines. An assessment considers broader patterns, including social communication, shared attention, play and repetitive behaviours, rather than deciding on autism from the number of words your child says or one behaviour you have noticed.
Mention concerns about limited pointing to share interest, reduced back and forth interaction, or repetitive patterns of play to your paediatrician alongside speech concerns. Any one of these observations needs context and isn't a diagnosis. When parents ask us when to worry about speech delay, we explain that checking the wider developmental picture helps identify suitable support without jumping to a label or overlooking other possible explanations.
When should I book a speech assessment and how do I start?
Book an assessment when milestones are being missed, communication is causing frustration, or your concerns keep returning, and arrange a paediatrician review too. Waiting without a plan can delay recognition of hearing difficulties or other developmental needs. At Next Steps Therapy Center in Selaiyur, you can share examples of your child's communication in Tamil and English, along with any hearing results or information from playschool.
To book a speech and language assessment, call +91 82202 30388; we're open Monday to Saturday, 9 am to 9 pm. You don't need a perfect word count before you call, just tell us your child's age and what you've noticed. Every family receives a parent app showing goals, session notes and home activities, so you can refer back to the plan around work and family routines.
