While I feverishly knock on wood, thus far we've done OK (kids ages 7, 4.5, almost 2 plus husband and I). A few small viral things that knocked the kids out for a day or two along with a couple colds, but otherwise nothing big. We did avoid some bigger group in December when my husband said there was a surge at the hospital of Covid and other respiratory illnesses, but we certainly haven't been shut-ins either. We had a Super Bowl Party, trip to the Mall of America with the kids, etc. I will say that post-Covid, I've been much more aware of hand sanitizing or hand-washing prior to eating when we are out with the kids, and if it's super crowded, I use a nasal spray that maybe helps with preventing illnesses, though we also did the basics like getting everyone their updated flu and Covid shots this fall. I feel like it's always a crapshoot with kids every winter. And it anyone is interested, CDC does a map every week for influenza-like respiratory illness, if you want to see what data is showing currently: https://www.cdc.gov/flu/weekly/usmap.htm.
