Meryl Streep - are her kids considered successful?

All four are on the margins of the entertainment industry.

Depends what folks consider "successful."

Personally, I don't even know any of their names or can name a single thing they've been in so I'd say, no, they're not bigtime yet. Their mother won an Oscar with like her third role in one of the biggest movies of that year in which she lobbied to get the character changed to be a better role. That's successful.

Mamie Gummer is a good actor. Not in her mother’s realms, but who is. Unfamiliar with the other 3 kids.
