Ninth-grader John Hilgert, 14, and junior Brianna Rodriguez, 16, were killed in the crush of spectators at NRG Park. Five of the 25 hospitalized were under the age of 18, including a 10-year-old who remains in critical condition.
They were among the many kids who attended Astroworld this weekend, and now, questions are circulating about whether it's safe for parents to leave their children unsupervised at these mega-events.

According to Astroworld's website, the sold-out, two-day event with 50,000 people in attendance did not have an age requirement. ABC News reached out to Live Nation, the event organizer, for further clarification on its age requirements but has not heard back.

Scott's high-energy performances are known for being chaotic and fun-filled shows with concertgoers encouraged to take part in a raucous nature involving mosh pits, crowd surfing and stage diving, the Associated Press reported.
In 2017, Scott was arrested after he encouraged fans to bypass security and rush the stage, leaving a security guard, a police officer and several others injured during a concert in Arkansas. In a separate incident, he was sentenced to one year of court supervision after pleading guilty to reckless conduct charges stemming from a 2015 incident in Chicago at the Lollapalooza music festival.
At the time, Chicago officials said Scott encouraged fans to vault security barricades. However, no one was injured.
"Make sure they have assigned seats and they're not in that standing-room-only area where there is that risk of there being a rush to the stage or stampede or even being smooshed by the crowd," said Ericka Souter, a parenting expert and author of "How to Have a Kid and a Life."
Parents should also ensure that their children determine a meeting point and create an exit strategy.
