how about a child who knows alot but they still act like their age
A child who possesses a lot of knowledge but still behaves in a manner typical for their age can be described as "intellectually advanced" or "knowledgeable." However, since they still display age-appropriate behaviors, you might also refer to them as "well-informed" or "intelligent for their age." They might also be considered "bright" or "curious," emphasizing their knowledge without implying that they are overly mature or serious for their developmental stage.
