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?


My question is if you took the average for all babies learning only one language, would you see them acquiring that language and speaking at different times based on the difficulty of the language, or around the same time, based on natural development?
