Mason is home now. He's eating dinosaur nuggets again. He's okay.

But I can't stop thinking about what that nurse said to me at 5 AM while I was sitting in a plastic chair next to his bed watching oxygen get pumped into his nose.

"Nothing the family had at home addresses the nose. The actual entry point."

She said she sees kids like Mason every single shift. Healthy kids. Vaccinated kids. Kids whose grandparents did everything right.

And they still end up there. Because nothing in the medicine cabinet kills the virus where it enters.

I sat in that chair looking at my grandson in his Spider-Man pajamas with a tube in his nose and I thought: he asked me if he was in trouble. He's five. And nobody told me there was something I could do about the entry point.

When I got home I couldn't sleep. I sat up until 3 AM reading everything I could find about what that nurse said.

Mason's runny nose on Monday wasn't the beginning. The virus had been in his nose since Saturday. And the saline spray I squirted up his nose while he screamed and pushed my hand away? Salt water. I was rinsing the surface while the fire burned underneath.

Then I found what she was talking about.

Povidone-iodine. Hospitals have used it in nasal passages for over 60 years. Pre-surgery. ICU protocols. One of the oldest antiseptics in medicine.

99% of respiratory viruses killed in the nasal passages in 90 seconds.

Mason's virus had four days. The answer was 90 seconds.

But hospital iodine burns. You can't use it at home every day. Then I found NutraMD — hospital-grade iodine combined with fulvic acid and aloe vera. No burn. No sting. No dryness. Gentle enough for daily use.

I use this on myself. Two sprays per nostril. Twice a day. Ten seconds. So that when my grandchildren come over with runny noses and coughs and whatever is going around their school, I am not the next person who gets sick and I am not the person who passes it back to them.

Five weeks now. Three weeks in, my other grandchildren came over. Both coughing. Both with whatever was tearing through their school.

My daughter stood in the doorway. "Mom, are you sure?"

After what happened to Mason, she had every right to ask. But I'd been using NutraMD twice a day for three weeks. And I was not going to be a grandmother who's too scared to hold her own grandchildren.

They climbed on me. Sneezed on me. Coughed in my face.

I didn't get sick.

One of them tested positive the following Monday. Same house. Same weekend. The only thing different was ten seconds twice a day.

I know how this sounds. I'm not selling anything.

I'm a 68-year-old grandmother who watched her grandson get a tube put in his nose because nobody told me there was something I could do about the entry point. $14,000 in hospital bills. $39 for the spray.

On my counter now. Every morning and every night. Especially before the grandkids come over.
