SEMINOLE COUNTY, Fla. -- One drowning and another near-drowning within six hours of each other had Seminole County sheriff's deputies pleading with parents to watch their children.

Friday afternoon, four-and-a-half-year-old Jade Hutagalong was all giggles and smiles with his mom Nadia. But there was a moment Thursday at a friend’s pool party when Nadia stared into the water and wondered if she'd ever see her son's smile again.

“I see him in the water floating, I didn't think twice, I just jumped in the pool and pulled him out,” said Nadia.

The pre-school teacher and camp counselor is CPR certified. And that saved her son’s life.

Jaden when to the hospital for observation just as a precaution.

An Oviedo family wasn't as fortunate Thursday. There was no one around when its toddler apparently fell into the pool and drowned.

Two incidents on the same day raise concerns for the Seminole County Sheriff's Office.

"We're encouraging parents to actively watch their children. Not just sit by the pool and read your magazine but (be) watching your child,” said spokeswoman Carrie Hoeppner.

Jaden was already in swimming lessons before this incident but he’d only mastered the shallow end of the pool.
