For those who are hoping that this is a violation of child labor laws, what are you hoping it accomplishes?
I have news for you, it won't stop the show. Say they have less hours to film a day, now instead of filming 3 days a week, they are filming 4 to get enough footage. Be careful what you wish for.
According to this article

"Child labor laws vary by state. Pennsylvania law permits kids who are at least 7 to work in the entertainment industry, as long as a permit is obtained and certain rules are followed. Kids can't generally work after 11:30 p.m., for example, or perform any place that serves alcohol.
The law allows performers younger than 7 to have "temporary employment ... in the production of a motion picture," and spend up to eight hours a day and 44 hours a week on set as long as their "educational instruction, supervision, health and welfare" needs are being met."
