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?
IIRC (and heavily paraphrasing here as this isn’t my specialty to say the least) most languages end up having about the same information density because most humans process language at the same speed. Some languages are spoken faster, but have less density in information, where others are slower but have higher information density. In The end it evens out, more or less
From that, without looking at other facts, I’d guess that babies learn it pretty much at the same speed, no?
you into linguistics?
