18-Month-Old Milestones: What to Expect
Your 18-month-old is in the thick of one of the most exciting and exhausting stretches of early childhood — becoming a person with opinions, preferences, and a will that very much has its own agenda.
Language and Communication
At 18 months, most toddlers use at least 10 words consistently, point to show things they find interesting (not just things they want), bring you objects to share excitement, follow simple one-step directions without a gesture, use words more than crying to communicate needs, and begin to imitate words they hear.
Worth a closer look: Fewer than 10 words in regular use, not pointing to share interest, not following simple directions, loss of words or skills previously had, or limited imitation.
Movement and Motor Skills
Most 18-month-olds walk independently and confidently, squat to pick something up and stand back up, begin climbing, throw a ball, use a spoon with some success, and stack two to three blocks.
Social and Emotional Development
At 18 months, most toddlers show clear attachment to caregivers, play alongside other children, imitate what adults do, express a range of emotions, and begin showing empathy.
Tantrums typically increase around this age — developmentally appropriate as toddlers have strong feelings and limited ability to express or regulate them.
Frequently Asked Questions
How many words should an 18-month-old say?
Most 18-month-olds use at least 10 words consistently. If your child is using fewer than 10 words in regular, functional communication, an evaluation with a speech-language pathologist is a reasonable next step.
Is it normal for an 18-month-old to have tantrums?
Yes. Tantrums are developmentally expected at this age.
