Re-read Zhangar's response to me, "No... Not until the child is 4 years old will it have a vocabulary and speech pattern similar to that of an adult."

That's not saying most, that's not saying "standard child development milestones" that's refuting my statement as a possibility entirely and stating 4 years old as the only age this milestone can be reached, which in my personal experience is not the case.

I was simply offering up the fact that 2 years old is a perfectly common age to be speaking well as a child, and shouldn't only be speaking a few small words at that point and used my own personal experience as an example. But like them, you seem to want to personally attack me instead of hearing a different perspective.
