Why Your Toddler Says 'No' to Everything (and Why That's Good)

The toddler no phase is often interpreted as defiance. More often, it’s a child discovering autonomy.

When toddlers push back, they are testing boundaries, language, and agency all at once. That doesn’t make the phase easy, but it does make it meaningful.
