[DC] How does the rest of the Justice League feel about Captain Marvel being a little kid?

Varies. Some people aren't even aware of it.

Generally speaking though, they're more upset about it if he keeps it a secret and then they find out accidentally cause they might see it as a significant detail to hide, that goes beyond the usual secret-identity stuff.

But given time they usually get over it since his track record as Cap. Marvel is usually pretty impeccable and end up treating him as something between a peer and one of the kid-sidekicks. They know he can stand with them in a fight, but won't ask him to do anything which they wouldn't feel comfortable asking a Teen Titan or Bat/Super-kid to do either.
