Joseph James Snyder knows how to make an entrance.
His sister, Jazmine McEnaney, knows how to help.
"Our mommy is pregnant, and her water just broke," Jazmine told a 911 dispatcher Monday morning.
Her mom, Krystal Garcia, was screaming in pain and panicking as she lay on the floor of her bathroom.
J.J. would be arriving two weeks early.
“If she wasn't there to call 911, there's no way I would have made it to that phone," Garcia said.
"(My contractions are) very bad," she told the dispatcher.
"I saw the baby's head," Jazmine said.
Dispatcher Emily Hall knew she had a doozy.
"When her mom would scream, she would scream with her," Hall said.
On speaker phone, hall gave Jazmine and Krystal instructions.
"Can you get some dry towels?" she asked Jazmine. "I want you to get in a comfortable position, preferably on your back."
Jazmine unlocked the door, and paramedics raced.
So did J.J.
Labor lasted only six minutes.
"The baby is out! The baby is out! Jazmine, is the baby out?" Garcia said on the recorded call.
"I was freaking out the whole time," Garcia said later. "She said he was out., but I didn't hear anything, I didn't know you don't hear anything till they get the stuff out. I was just hearing silence. I thought I was giving birth to a dead baby."
At the other end of the line, Hall was concerned too.
'It was not crying yet. I just said my little prayer at that point," Hall said.
Paramedics arrived and quickly realized J.J. was just being much quieter than his mom and sister, and he was fine.
"You did an amazing job helping to deliver your baby brother," said a certificate given to Jazmine by hospital staff at TGH.
"She definitely stayed calm when she needed to," said Garcia. "I was hysterical."
J.J. weighs 5 lbs, 10 oz. Mother and baby are doing well.
