Actress Soleil Moon Frye is urging parents to watch out if their kids are showing symptoms of COVID-19 and have them tested if they get sick. She gave this advice after she found out that three of her children were positive for the virus.

The “Punky Brewster” star shared her worrisome experience in an Instagram post Monday.

“If your children are having symptoms, please get them tested. I thought my son had a cold or a fever; I did not know that he had COVID-19,” Frye, 44, captioned the photo that showed her posing with her children in what seemed to be a swimming trip. The kids were seen holding popsicle sticks as they posed before the camera.

“With the encouragement of our doctor I had him tested – he tested positive. I was on my way to a work trip, rushed home and two of my other children tested positive as well,” she said.

Frye has four children with her ex-husband, producer Jason Goldberg: Poet, 15; Jagger, 13; Lyric, 7; and Story, 5.

"I want to protect my babies, love them, make them all better, take away the burning fever and tummy aches," she said, adding: "I have tried to smile through the fear and nurture them. I have shed many tears. It has brought up a lot for me."

The actress also opened up about the tremendous scare she felt due to the experience but she said it also brought out in her the kind of gratitude that she has never known before.

"I know how incredibly fortunate we are. My kids have been able to heal together and support each other through this, we have a doctor we trust, and hospitals close by. We are able to lean on one another. My heart breaks for the lives that have been lost and knowing how so many do not have the same things that we have or the chance to be with their loved ones throughout this."

Frye also expressed her gratitude to the doctors and other frontline workers for their service during the pandemic.

“I continue to have the deepest respect for all of the caretakers on the frontlines, doctors, health workers, and volunteers, I have more love and compassion for single parents, grandparents, aunts, uncles, friends, and extended families that come together and jump in when needed,” she pointed out.

The mother of four said she has no idea how her kids contracted COVID-19 as she and other family members tested negative for the virus.

“That is part of the mystery in this, how hard it is often to trace and how easy it is to spread,” Frye said. “Please be safe: much love to you all.”

Frye recently helmed the “Kid 90” documentary on Hulu where she explores her past experiences as an actress when “Punky Brewster” ended, including her experimentation with drugs, grieving young friends who died too soon and swooning over A-list crushes.

The documentary includes a look back on the day Frye lost her virginity to her long-time crush, Charlie Sheen, according to USA Today.
