Blog › 婴幼儿 (0–3岁) › 18个月语言里程碑：何时需要采取行动，何时可以等待
Key Takeaways
Word count alone is a weak predictor — the red flags that actually matter are qualitative: no pointing, no joint attention, and especially regression of any skill.
18% of children with fewer than 10 words at 18 months develop completely normal language by age 5 with zero intervention.
For bilingual children, always count total vocabulary across both languages — single-language screens systematically underestimate true language development.
Research Data
Relative predictive weight of each red flag for persistent language delay at age 5. UK Millennium Cohort Study (2021).
18% of children with fewer than 10 words at 18 months had completely normal language by age 5 with no intervention — but the red flags to watch for are qualitative, not just word counts (UK Millennium Cohort Study, 2021).
在18个月前后，许多新加坡家长开始互相比较——在亲子班、育儿论坛、或与祖父母讨论——几乎每次比较都会带来焦虑。
关于早期语言发展的研究，既比通常看到的里程碑令人安心，也比它们更加细致。
常被引用的基准——12个月10个词、24个月50个词和两词组合——是人口中位数，而非最低门槛。大约一半正常发育的孩子在任何年龄都低于这条线。
2021年英国千禧年队列研究（18,000名儿童）发现，18个月时词汇少于10个的孩子中，18%在5岁时语言能力完全正常，无需介入。
新加坡儿童通常同时接触两种或更多语言。双语幼儿的总词汇量与单语同伴相当，但词汇分布在不同语言中。建议寻求能评估双语的语言治疗师。
