On Wednesday, Momi Wilkins renewed her certification for infant CPR. On Saturday afternoon, she used her newly refreshed knowledge to save a 2-year-old girl from drowning in a Hawaii Kai residential pool.

Wilkins was at the Peninsula at Hawaii Kai residential complex pool with her 9-year-old daughter Kamakaiwa and three other children she was baby-sitting and had been talking to the 2-year-old’s mother just before the incident.

"The little girl had been swimming with a vest but then took the vest off," Wilkins said. "I told the mother that I didn’t think that was a good idea."

A few minutes later, Kamakaiwa Wilkins noticed the child face-down at the bottom of the pool and screamed for help before trying to rescue the child herself.

Momi Wilkins said she jumped in, pulled the child out and performed CPR for six minutes until paramedics arrived.

The child was taken to the hospital in serious condition but was later upgraded to stable condition, Wilkins said.

The incident happened about 2:20 p.m. Wilkins said there were about 15 children in the water at the time.

Wilkins, whose prior CPR certification expired in 2010, said she renewed her certification last week as a requirement for her new job as a cruise director.

"One of the first things I did when I got home was call my employer and thank him for making me take that class," Wilkins said.
