Early signs of Developmental Language Disorder at 6–9 months
Developmental Language Disorder is not diagnosed at 6-to-9 months, as language is only just emerging. At this age we watch healthy pre-language building blocks instead: babbling, turning to sounds, eye contact and shared attention. A baby who does not react to any sound or voice needs a prompt hearing check, but DLD itself becomes meaningful only in the toddler and preschool years. Only a qualified clinician can assess.

At six to nine months, your baby is just beginning the beautiful journey into sound and connection — so it helps to know what truly matters now, and what can wait.
In short
Developmental Language Disorder (DLD) is not diagnosed in a 6-to-9-month-old — language is only just emerging, and a formal label this early would not be clinically meaningful. What we can watch at this age are the early communication building blocks: babbling, response to sound, eye contact and shared attention. If these are clearly absent or your baby does not seem to react to sounds, a gentle developmental check is wise — but most babies are simply finding their own pace.
What is appropriate to observe at 6–9 months
DLD is a difficulty with understanding and using language that becomes recognisable later — usually from around 2–3 years onward, once a child should be combining words. At 6–9 months, instead of looking for "disorder," we watch for the healthy pre-language milestones:
Hearing and listening
- Turns towards your voice or a sound
- Startles or settles to familiar sounds
- Seems to enjoy music, rattles and your singing
Babbling and voice
- Makes cooing and then babbling sounds ("ba-ba", "da-da") by around 6–9 months
- Takes vocal "turns" — babbles back when you talk
Connection and shared attention
- Looks at your face, makes eye contact, smiles back
- Follows your gaze or a point, reaches and gestures
Gentle things worth a check (not a diagnosis): a baby who does not react to sounds or your voice at all, makes very few or no sounds, or shows no eye contact or social smiling. The most important first step here is always a hearing check, because hearing underpins all early language.
When language assessment becomes meaningful
A true conversation about DLD belongs to the toddler and preschool years, when we can see how a child understands instructions and puts words together. For now, the right stance is warm, watchful monitoring — and acting promptly on any hearing concern, since early hearing support protects later language.
The Pinnacle way
At Pinnacle Blooms Network, we celebrate every coo, babble and shared smile as real communication, and we coach families to build these naturally through play and talk. If you have any worry, our team begins with a gentle developmental and hearing-focused screen rather than a label — explore speech therapy, learn about Developmental Language Disorder, and see how a clinician-administered AbilityScore® works. Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care — never from an online list. With 2.5 billion+ data points and 25 million+ therapy sessions behind us, we focus on what your baby can build next.

Something to notice. Something to discuss.
What to notice
Seek a prompt hearing check if your baby does not react to sounds or your voice at all, makes very few sounds, or shows no eye contact or social smiling — hearing underpins all early language.
In everyday life
Talk, sing and babble back to your baby through the day — pause after your baby's sounds and 'reply', so they learn the rhythm of conversation long before words arrive.

Bring your questions to a first visitQuestions families ask
Can Developmental Language Disorder be diagnosed in a baby?
No. DLD is not diagnosed in infancy because language is only just beginning to emerge. It becomes recognisable in the toddler and preschool years, once a child should be understanding instructions and combining words. At 6–9 months we watch healthy pre-language signs like babbling and shared attention instead.
What should my 6-to-9-month-old be doing with sounds?
Around this age most babies turn towards your voice, babble strings like 'ba-ba' or 'da-da', take vocal turns when you talk, and enjoy music and singing. They also make eye contact and smile back. These are the building blocks of later language.
When should I worry about my baby's communication?
A gentle check is wise if your baby does not react to sounds or your voice at all, makes very few or no sounds, or shows no eye contact or social smiling. The first step is usually a hearing check, since hearing underpins all early language.
