What should a 15-month-old be doing?
At 15 months most toddlers walk on their own, say a few words while understanding far more, point to ask and show you things, and copy what you do. The clingy separation-anxiety phase often peaks now. Here is what is typical at 15 months across movement, speech, sleep and feeding, plus the few signs worth a pediatrician chat.
Age: 15 months.
Most children at this age: walk on their own, say a few words and point to ask, follow a simple direction with a gesture, and copy what you do.
Common concerns this month: few words yet, the clingy separation-anxiety phase, dropping to one nap, picky eating starting. Most are a normal part of development.
Typical sleep: 11 to 14 hours a day, often moving from 2 naps to 1 around now.

Frequently asked
- What should a 15-month-old be doing?
- Most walk on their own, say a few words while understanding far more, point to ask and show things, follow a simple direction with a gesture, and copy what you do. Wide ranges are normal.
- How many words should a 15-month-old say?
- Often just a few clear words beyond "mama" and "dada", with pointing and understanding well ahead. Word counts grow fast toward 18–24 months.
- Is separation anxiety normal at 15 months?
- Yes. It often peaks between 12 and 18 months as memory develops, and it's a sign of secure attachment.
- When do toddlers drop to one nap?
- Often between 12 and 18 months. Signs include fighting the second nap or a late nap pushing bedtime too late.
- Should I worry if my 15-month-old isn't walking?
- Most walk by 12–15 months. Not walking by 18 months is worth a pediatrician chat; cruising and pulling up are good signs along the way.
