COLLIER COUNTY, Fla - An early holiday weekend message to keep your family safe while out by the water. It has been a deadly year on Southwest Florida's water. This year, four Collier County children have died from drowning, including a two year old just last Friday.

Sue Lester knows all too well, how every second matters when it comes to children and the water. "She slipped behind me. It was an instant," says Lester. "I came out and said where's Zoey and she was gone."

The number one myth when it comes to drowning is that children will scream and make noise, but drowning is known as the silent killer. "My husband said she's not in the pool because it was like glass, not even a ripple. She didn't splash, she didn't scream she didn't anything she just went straight to the bottom," says Lester.

Lester's granddaughter Zoey is now eight years old and 100 percent okay. But Lester knows those two seconds she turned away could've been fatal.

"Another misconception is that you'll have some time to react and you really only have seconds to intervene before the body starts shutting down so it's imperative to find the child and initiate CRP as quickly as possible," says Dr. Todd Vedder is a community pediatritian for NCH and chairman of the Safe & Healthy Children's Coalition.

The groups top priority is to prevent drownings in the community and make parents realize that it can happen to anyone. "We can't see another child's life get snuffed out by something that's 100 percent preventable," says Dr. Vedder. "Each of these cases can be prevented."
