Ralph fell to the floor as other disappointed riders left the queue line.
Ralph was “sobbing, screaming, rocking, hyperventilating, and truly struggling to breathe,” Lenore Koppelman wrote in her post.
But what happened next was not what you would expect in a crowded theme park.
A worker from the ride told the family they didn't have to leave and to let Ralph work through his disappointment. Then the worker, Jennifer Whelchel, lay down on the floor next to Ralph to comfort him, CNN reported.

“She rested next to him while he cried his heart out, and she helped him breathe again. She spoke to him so calmly, and while (he) screamed and sobbed, she gently kept encouraging him to let it all out.”
Whelchel also told people not to stop to watch and take photos of Ralph as he went through his episode.

Whelchel, who is called "Mama Jenn" by coworkers, has a nephew about the same age as Ralph who also has autism. She lay on the ground out of instinct and learning how to deal with her nephew's meltdowns. She told the Post she wanted to be on Ralph's level but didn't want to impede on his space.
Whelchel said she and other Universal employees do go through sensitivity and awareness training, but the mother of two said getting on Ralph’s level was not part of that training.
After about 10 minutes, Ralph calmed down, got a drink of water and sat up, giving Whelchel an unprompted high five, The Washington Post reported.
She also pulled some strings to let Ralph have a on-the-house, $50 shopping spree at the park’s Spider-Man store.
The family plans to travel back to Orlando so Ralph has a chance to ride the Spider-Man ride, CNN reported.
