Early signs of Developmental Language Disorder in a 1-year-old boy

At one year, a little boy is still warming up his voice — so when does quietness need a closer look rather than just more time?

In short

At 12 months, Developmental Language Disorder is not yet diagnosed — language is only beginning, and there is wide, healthy variation between children. What you can watch are the early communication building blocks: babbling, gestures like pointing and waving, responding to his name, and understanding simple words. If several of these are not appearing, it is worth a gentle developmental and hearing check — not a cause for alarm.

What's appropriate to watch at 12–18 months

A formal DLD picture (ICD-11 6A01.2) usually becomes clearer from around age 2–3, once spoken words and word combinations are expected. At one year, look instead at these foundations:

Listening & understanding

• Turns or responds when you call his name
• Looks towards familiar objects or people when named ("Where's Papa?")
• Notices and reacts to everyday sounds and your voice

Sounds & early talking

• Babbles with varied sounds and rhythm ("ba-ba-da-da")
• May have one or two clear words around the first birthday
• Copies sounds or simple actions back to you

Gestures & connection

• Points, waves, or reaches up to be picked up
• Shares attention — looking from a toy to you and back
• Enjoys back-and-forth play, smiling and turn-taking

Gentle flags worth a check by 12–18 months: no babbling at all, no gestures like pointing or waving, not responding to his name, or any loss of sounds or skills he once had. A hearing check is always a sensible first step, as glue ear and hearing differences are common and very treatable.

When assessment becomes meaningful

Language assessment for DLD is most useful from around 2 years, when single words and early two-word phrases are expected. Before then, the focus is monitoring the building blocks above and ruling out hearing concerns. Persistent parental worry is itself a good reason to ask — you know your child best.
