Bilingual Vocabulary Milestones
For a bilingual two-year-old, one of the most helpful bilingual vocabulary milestones is around 50 meaningful words in total, counted across every language she uses, alongside the start of two-word combinations like “more milk” or “mama go.” The key difference for bilingual families is that this count is combined across all languages — Cantonese, Mandarin, and English together — rather than measured against English alone, which is where a lot of unnecessary worry starts.
Why can’t I just count my child’s English words for bilingual vocabulary milestones?
Because that only shows part of the picture. Bilingual toddlers typically develop different strengths in each language depending on how much they hear and use it — a child who spends most weekdays at an English-speaking childcare and most evenings and weekends with Cantonese-speaking grandparents will naturally develop each language at a different pace. What matters developmentally is the combined total: a two-year-old with 30 Cantonese words and 25 English words has a vocabulary of around 55 words, comfortably in the typical range — even though her English alone might look “behind” an English-only peer at daycare.
What does typical language use look like around age two? Around this age, most toddlers — bilingual or monolingual — are moving from single words into short combinations: two-word phrases that combine a noun with a verb or descriptor, like “no cookie,” “dada up,” or “car gone.” For bilingual toddlers, these combinations might appear in one language, the other, or a mix of both (for example, “要 more” or “car 走了”) — and mixing at this stage is completely normal, not a sign of confusion. You should also expect steady week-on-week growth in vocabulary rather than a plateau, even if that growth is spread across two languages rather than concentrated in one.
What if my two-year-old has far fewer words than this, combined as bilingual vocabulary milestones?
If your toddler’s combined vocabulary across all languages is well below this range, and especially if she also has limited gesture use (like pointing or waving), limited babbling history, or difficulty understanding simple instructions in any language, that combination is worth having properly assessed. The distinction that matters clinically isn’t “how many English words” — it’s “how is she communicating overall, across every language and every mode of communication available to her.”
How do I track this accurately at home? Keep a simple running list for a week or two of every word your toddler uses meaningfully — across Cantonese, Mandarin, and English — including approximations (like “nana” for grandma or “ba” for bus). Add them all together rather than sorting by language first. This combined total, alongside whether she’s starting to combine words and how she’s using gesture and play to communicate, gives a far more accurate picture than checking her progress against English milestones alone.
Does it matter which language she talks more? Not for this milestone check. What matters at two is the combined total and the emergence of word combinations — not which language carries the bigger share. It’s completely normal for one language to be noticeably stronger than the other at this age, usually reflecting whichever language your toddler hears and uses more often day to day. That balance often shifts over time as circumstances change — more childcare hours, a new sibling, a house move, more time with grandparents — and a stronger language today doesn’t lock in as her stronger language forever. Comparing her Cantonese to a Cantonese-dominant cousin, or her English to an English-only daycare friend, will always make one side look “lighter” by comparison, which is why the combined total is the number worth watching, not either language in isolation.
Where to go from here for bilingual vocabulary milestones?
If your two-year-old’s combined vocabulary seems low, or you’d simply like a clear, professional read on where she’s tracking across both her languages, a bilingual speech pathology assessment gives you an accurate answer rather than a guess based on English alone. Our team can also point you toward the right next step, whether that’s individual therapy or one of our language-rich group therapy programs as she gets a little older.

我的雙語兩歲孩子應該懂得多少詞彙？一份給廣東話／普通話與英語家庭的里程碑指南
對一個雙語兩歲孩子而言，一個有用的參考基準,是合共約50個有意義的詞彙——把孩子使用的所有語言合併計算，同時開始出現「more milk」或「媽媽走」等雙詞組合。對雙語家庭而言，關鍵的分別在於，這個詞彙量是把廣東話、普通話及英語全部合併計算，而非單以英語衡量——而這正是不少不必要憂慮的起點。
為何不能只計算孩子的英語詞彙？
因為那只反映了部分圖像。雙語幼兒在每種語言的發展程度，往往取決於接觸及使用的多寡——一個平日大部分時間在英語幼兒園渡過、晚上及週末則與說廣東話的祖父母相處的孩子，兩種語言自然會以不同步伐發展。真正重要的是合併總量：一個懂30個廣東話詞語及25個英語詞語的兩歲孩子,詞彙量合共約55個，屬於正常範圍之內——即使她單以英語計算，看似落後於純英語環境的同齡孩子。
兩歲左右的語言運用大概是怎樣的？ 這個年齡的幼兒——不論雙語或單語——大多正由單詞過渡至簡短組合：把名詞與動詞或形容詞結合的雙詞短句，例如「no cookie」、「爸爸抱」或「car 走咗」。對雙語幼兒而言，這些組合可能只出現在其中一種語言、另一種語言，或兩者混合（例如「要 more」或「car 走了」）——這個階段的語言混合完全正常，並非混淆的跡象。你亦應預期詞彙量會逐週穩定增長，而非停滯不前，即使這個增長分散在兩種語言之中,而非集中在一種。
如果我兩歲的孩子詞彙量遠低於此,怎麼辦？
如果孩子把所有語言合併計算後的詞彙量明顯低於這個範圍，尤其如果她同時手勢運用有限（例如指物或揮手）、牙牙學語的歷史有限，或難以理解任何語言的簡單指示，這種組合便值得作正式評估。臨床上真正重要的分野，並非「懂多少個英語詞語」，而是「她整體上——透過每一種語言及每一種溝通方式——是如何溝通的」。
我在家中如何準確地追蹤這些？ 可以嘗試一至兩星期內，記錄孩子有意義地使用的每一個詞語——涵蓋廣東話、普通話及英語——包括近似的發音（例如用「lala」代表姐姐,或「巴」代表巴士）。把它們全部加起來計算，而非先按語言分類。這個合併總量，連同她是否開始組合詞語，以及如何運用手勢及遊戲溝通，會比單以英語里程碑作對照，提供準確得多的圖像。
哪種語言她說得較多重要嗎？ 就這個里程碑而言並不重要。兩歲時真正重要的是合併總量,以及雙詞組合的出現——而不是哪種語言佔的比重較大。這個年齡其中一種語言明顯較強屬於完全正常，通常反映孩子日常接觸及使用較多的語言。這種平衡往往會隨情況改變而轉移——更多的託兒時數、新添的弟妹、搬家、與祖父母相處時間增多——今天較強的語言，不代表永遠都是她較強的語言。把她的廣東話與一個以廣東話為主的表親比較，或把她的英語與一個純英語環境的幼兒園朋友比較，總會令其中一方看似「較弱」，這正是為何合併總量才是值得留意的數字，而非單獨看任何一種語言。
接下來可以怎樣做
如果你兩歲孩子的合併詞彙量看似偏低，或你只是想清楚了解她在兩種語言上的專業評估結果，一個雙語言語治療評估，能給你一個準確的答案，而非單憑英語猜測。我們的團隊亦能在她稍大後，指引你考慮個別治療，或我們其中一項語言豐富的小組治療課程,作為合適的下一步。
