Your 18-month-old: milestones and what to expect

Q: What milestones should a 18-month-old have?

Most toddlers do these by 18 months (CDC): Moves away from you, but looks to make sure you are close by · points to show you something interesting · puts hands out for you to wash them · looks at a few pages in a book with you · helps you dress them by pushing an arm through a sleeve or lifting up a foot · Tries to say three or more words besides "mama" or "dada" · follows one-step directions without any gestures, like giving you the toy when you say "Give it to me." · Copies you doing chores, like sweeping with a broom · plays with toys in a simple way, like pushing a toy car · walks without holding on to anyone or anything · scribbles · drinks from a cup without a lid and may spill sometimes · feeds themselves with their fingers · tries to use a spoon · climbs on and off a couch or chair without help.

Eighteen months is a big CDC stop: walking without holding on, three or more words besides mama and dada, scribbling, and drinking from a cup without a lid. Many children also walk away to explore and keep checking that you are close by. The AAP recommends a developmental screening at this age, worth asking about at the well-child visit.

What most children this age can do

Social & emotional: Moves away from you, but looks to make sure you are close by · points to show you something interesting · puts hands out for you to wash them · looks at a few pages in a book with you · helps you dress them by pushing an arm through a sleeve or lifting up a foot.

Language & communication: Tries to say three or more words besides "mama" or "dada" · follows one-step directions without any gestures, like giving you the toy when you say "Give it to me."

Movement & thinking: Copies you doing chores, like sweeping with a broom · plays with toys in a simple way, like pushing a toy car · walks without holding on to anyone or anything · scribbles · drinks from a cup without a lid and may spill sometimes · feeds themselves with their fingers · tries to use a spoon · climbs on and off a couch or chair without help.

What you might notice

No more fussier stretches were described in the research after week 62. Many toddlers this age walk away to explore but keep checking that you are close by. That is an 18-month milestone, not clinginess to fix. Some days can still feel harder, and timing varies a lot between children.

What can help this month

Let your child "help" with simple chores, look at a few book pages together, and offer a spoon and a cup without a lid, even if it gets messy. Short, simple directions work best ("Give me the ball"). Expect a lot of spilling while they practice.

And you: Messy meals and slow mornings are part of this stretch. You can lower the bar for the day and still be doing a great job.

Talk with your pediatrician if…

Talk with your doctor

Your baby is missing one or more of the milestones above by 18 months, or has lost skills they once had. That is the CDC's own advice: don't wait, talk with the doctor and ask about developmental screening. And if you're simply worried, that's reason enough to call.

Coming up: after this window comes "almost two" (weeks 78 to 104). No deadlines, windows.
