When should I worry that my two year old is not talking yet?

What the evidence says

Some variation in toddler talking is normal, and many late talkers catch up. But specific signs are worth flagging to your pediatrician: not combining words by 2 years old, not being understood by family half the time by age 2.5, losing words or skills they used to have, not responding when called by name, or showing intense fixation on objects rather than using words to ask for things.

Language delay is actually the most common type of developmental delay, and about 1 in 5 children will learn to talk or use words later than other kids their age. Most of these late talkers do fine, but a good chunk have an underlying issue like hearing loss, a language disorder, or autism spectrum disorder that benefits from early identification.

You don't need to wait for a doctor's referral to get things moving. You can contact your local early intervention program directly for a free evaluation if your child is under 3, at the same time you raise concerns with your pediatrician. If your doctor says to wait and see but you're still worried, it's completely fine to ask for a referral to a speech-language therapist or developmental specialist, or get a second opinion.

The earlier concerns are addressed, the sooner your child can get support, and research shows structured parent-led language coaching programs can meaningfully improve outcomes for toddlers with expressive language delay by age 3.
