(ELI5) when babies are raised with bilingual families, are they learning it as just one jumbled language, or as two separate languages?

Question

Also would it become difficult to discern and seperate them when they join school for example, and interact with people that only speak one

Answer 1

So from my personal experience: when raising a child billingual it’s important to seperate the languages. My mother only talked Hungarian with me, my dad only German. I am pretty sure that I could seperate the languages pretty early so I would guess they realize pretty fast that these are two different languages.
