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.

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.
