Her daughter, Allison, dove in the pool and made several tries to pull her mother to the shallow end of the pool.

Once she got her mother to the shallow end, she pulled her head above the water and turned her mother over so she could breathe.

Allison then went inside her house for help.

Allison's sisters and her aunt, Tedra Hunt, came out to get Anderwald.

The entire thing was caught on home security cameras.

"She was really heavy, and I could only get the top part of her out, and then (Tracy's) other daughters ran over and helped me get her out, and so, Allison was able to do that on her own," Hunt, 32, told KRIS. "It's a miracle."

Anderwald, 34, said she woke up in the hospital. She does not know why she had the seizure and she said she has never had one before, but she is thankful for her hero.

"The doctors explained to us that had Tracy been under water any longer, she probably wouldn't be with us right now," Hunt told ABC News. "It is truly amazing that this little girl, who's actually also pretty small for her age, was able to save my sister."

Anderwald was discharged from the hospital on Tuesday and is doing well. She plans to follow up with a neurologist to determine what caused the seizure.

"Allison's been swimming since she was 2-and-a-half," Anderwald said. "She's our little mermaid and my little hero."
