ELI5: How many languages can a baby learn naturally during the language developmental stage?

Most kids learn one, maybe two languages during this stage, but what's to stop someone from learning, say, five or ten languages? How many is too many for them to process? Am genuinely curious about this.

Unfortunately there isn't going to be a concrete answer.  Theoretically any child could learn an infinite number of languages, but in order to learn any number of languages, whether 1 or 1,000, it takes immersion in the language.  Computers and flash cards can't provide this immersion; it takes human interaction with fluent speakers.  It would be difficult to provide this type of environment to say the least.   Just imagine the scenarios that would have to take place for a child to be immersed in 5-6 languages.  Possible?  Oh yes.  But, also a very atypical upbringing. 

Children learning multiple languages have been studied and their ability to avoid confusion is something that has fascinated researchers.
