Worrying About DLD in a 6-to-9-Month-Old

If you're watching your baby babble and wondering whether their language is on track, that gentle alertness is exactly the loving instinct that serves children well.

In short

At 6–9 months it is far too early to diagnose Developmental Language Disorder — DLD is a label applied much later, usually after age 4–5, once a child has had real opportunity to build spoken language. Your baby is still in the foundations stage: babbling, listening, turn-taking and connecting sounds to faces. So rather than worrying about DLD now, the kind thing is to enjoy and gently observe these early communication milestones, and raise a flag if a few of them seem missing.

What is actually appropriate to watch at 6–9 months

DLD is not about saying words yet — at this age there are no "DLD signs" to hunt for. Instead, these are the healthy early-communication building blocks to notice:

• Babbling — repeated sounds like "bababa", "dada", "mama" emerging and growing
• Responding to voice — turning towards you when you speak, quietening to a familiar voice
• Turn-taking — making a sound, pausing, and "answering" you back
• Responding to name — looking up when called (often by 9 months)
• Sharing attention — following your gaze or a point, enjoying peek-a-boo
• Reacting to sound — startling, turning to noises, enjoying songs

A single quiet day is nothing to worry about. What is worth a gentle check is the consistent absence of these — for example, very little or no babble by 9 months, not responding to sound at all, or no eye contact and shared smiling. Because hearing is the foundation of language, any concern here should begin with a simple hearing review.

When language assessment becomes meaningful

Meaningful language assessment for DLD comes later — typically from the toddler and preschool years onward — when first words (around 12 months) and word combinations (around 18–24 months) are expected. For now, a routine developmental and hearing check is the right route, not a DLD work-up.

Next step — If your baby is not babbling or responding to sound by 9 months, the kindest first move is a hearing and developmental check. Book a developmental check with a Pinnacle clinician.
