Our oldest is 5 and I'm pretty sure we're still sending him off on his way to kindergarten (public). He's super high energy and at home, barring Lego or puzzles, he has the attention span of a flea. I don't know what fuel he runs on but he dropped all naps at 16 months old, sleeps maybe 10 hours on a good night, and can still run laps around me. He's currently running laps around the house as I type this.
He loved preschool, he was the popular kid at class. When my wife would drop him off, half the kids would run over to say 'hi' to him (which they did for none of their other classmates). His daily behavior and attitude has been sharply affected since school ended - long story short, he really needs that socialization.
Our school district is in a good financial position and everything is still on track to resume in-person elementary (at least) in the fall. As of now I believe teachers and older kids will be required to wear masks but from the way things are trending, kindergarten and possibly first grade may not have to wear masks on a daily basis. I have no idea what it means for recess.
We talked about homeschooling him for a while, because there was indication a few months ago that fall elementary would be virtual, and there's no way he can sit in front of a laptop for hours at a time with teachers and classmates he's never met. Problem is, we have two younger boys at home (including a 7 month old) and there's no way we could reasonably homeschool while juggling work and the other two.
We also briefly talked about private school, but the cost is just too high and although my wife and I both attended private elementary school, neither of us feel like we benefited any more than if we had gone to public school. So, we affirmed our decision to send him to public school and as of now, we're going to have him attend in the fall unless the school has to switch to virtual learning. If they do switch to virtual learning, we're going to have to explore some alternative options but I don't think it will come to that point.
There's always the risk of the virus, but there's also always the risk of other illnesses from school. We've already been through HFM (and as an adult, that's not anything I would want other adults to have to live through), a number of colds, and a GI bug. Vaccine or not, I think we as a household have fully accepted the potential risk of Covid. We'd be ready to isolate ourselves if we knew one of us had it but we just can't keep our boys sheltered anymore, especially the kindergartener-to-be - he, more than anything else, needs to be playing with kids his age.
