Like, English is a famously difficult language, and Spanish is supposed to be easier. But babies learn English or any language instinctually.
So do babies learn faster if the native language is easier, or do they acquire language at a constant rate depending on their brain development or whatever?
English is an easy language, easier than Spanish IMO. If the child lives in a context where the language is spoken all the time doesn’t matter when you talk about a first language.
