The First Native Scale

The five stages

Each stage is defined by observable behaviour — what the child actually does with the language — rather than by test scores alone. Parent quotes are drawn from real diagnostic sessions (translated from Russian; names changed).

Stage 1

Living language

The language works in full — for routines, feelings and thought.

  • Tells stories, argues, makes jokes
  • Can explain what upset them, and why
  • Chats freely with grandparents about their life
Stage 2

Kitchen language

"We only speak our language at home" — but it has narrowed to household routine. The language of feelings is already going.

  • "Eat up, get dressed, tidy up" — understands and responds
  • "How was your day?" — "fine", or silence
  • Cannot tell you what made them upset or excited
"Getting anything out of her is very hard. Very hard."mother of Olivia, 5 · UK
Stage 3

Answers in the majority language

Understands everything — but has stopped answering in the first language. The language has become one-directional.

  • You speak your language — the child replies in the majority language
  • Phrases built on the other language's grammar appear
  • "Allows" you to speak your language to them — as a favour
"Fine, okay — with you I'll speak Russian."Richard, 6 · Germany
Stage 4

"I don't want to"

Every phrase in the first language has become an effort — and the child starts refusing.

  • Direct refusal: "I don't want to", "I won't"
  • A pause before answering — as if translating
  • Frequently asks: "how do you say it in our language?"
"With me he doesn't want to speak Russian. It's very hard to make him."mother of Sasha, 9 · USA
Stage 5

"I can't"

The first language has become foreign: the child thinks in the majority language and translates.

  • Words no longer come by themselves — the other language surfaces first
  • "I know what it is. I just don't know what it's called."
  • Calls for help in the majority language
"I think he already thinks in English. The rest he simply translates."mother of Alik, 6 · Canada

Movement along the scale

The stages are ordered but not fated. Movement down the scale is driven mostly by exposure and necessity: when the first language stops being needed — because the child is understood in the majority language anyway — it narrows, then goes silent, then goes passive. Movement back up is possible at every stage; in clinical practice, recovery from stages 2–3 is typically measured in months, from stages 4–5 in longer, structured work.

Two findings behind the scale's design: parents typically notice the process at stage 3–4, while it begins at stage 2; and what is lost first is not household vocabulary but the language of emotion and abstraction — the part of language on which the parent-child relationship depends.
