This happened to us too, until I heard the podcast about Vitamin D. Nipped that in the bud almost immediately.
I heard about vitamin D during covid, and that and hand sanitizer are the only 2 things we still do. I haven't been sick for a few years. Before covid (and vitamin D supplements), it was at least 25 days sick every year, if not more.
What's that? Any particular dosage?
This is Linus Pauling all over again.
