15 Month Old Toddler

Toddler

What to expect at 15 months — approximately 1 year 3 months old.

Welcome to 15 Months. Your little baby is now firmly in toddler territory. Many 15-month-olds are constantly on the move — walking, climbing, exploring, and investigating have become full-time jobs. Curiosity is stronger than ever, and your toddler wants to learn by doing everything themselves. This stage can be both wonderful and exhausting.

Frequently asked questions

Should my toddler be walking?

Many toddlers walk by 15 months, although the timing varies and some healthy children begin walking a little later.

How many words should my child say?

Language develops at different speeds. Understanding is often much more advanced than speaking at this age.

Is it normal for my toddler to say 'no' constantly?

Yes. Learning independence often involves testing boundaries and expressing preferences — it is a healthy part of development.

Why does my toddler want to do everything themselves?

Developing independence is one of the major developmental goals of this stage.
