LEWISVILLE (CBSDFW.COM) – A toddler’s life was in the balance as a dramatic 911 call unfolded in Lewisville.

“Help me. She’s dead. My granddaughter was in the pool and I don’t know…,” were the first words out of the grandmother’s mouth during the February 7 call to 911 supervisor Angela Sherrod.

“Your training just kicks in,” recalled Sherrod.

The caller said she’d found her back door open and her 18-month-old granddaughter in the pool.
Sherrod guided the grandmother with instructions on how to clear the toddler’s airway and perform mouth-to-mouth.

“I can’t do all this,” says the caller in a 911 recording.
“Yes, you can. Yes, you can,” responds Sherrod.

It’s not the first reported drowning Sherrod has handed but it is the first that ended like this –

“I hear her. Can you hear her?,” asked the grandmother.
“Is that her crying?” asked Sherrod.
“Yes, yes, yes,” said the caller.

“It wasn’t until the very end that it hit me that I knew her,” says Sherrod. “I used to live down the street from her. Our kids grew up together. And that’s when it was like, ‘This is Angela.'”
You okay?” asked Sherrod.
“Yeah, Angela. This is my grandbaby,” said the caller.
“I know. You did a good job, okay?” said Sherrod.

Sherrod says this was one of her best 911 calls ever.

Paramedics rushed the girl to a Dallas hospital. The family says she’s doing well.
