N.B.
My parents weren't all that involved.
They showed up for Christmas performances, end of year graduations or awards ceremonies, things that were not the every day thing.
Other parents were there for each in class party we had. The home room parents were in and out all the time. Planning things then doing those activities.
Kids think their achievements are a big deal. When parents don't even acknowledge these achievements the kids learn to discount them and don't strive to earn them. Like good grades. If parents think a B is awful and abnormal and horrible then a kid who really struggled through a class and worked hard but only got a B feels like they will never make it and they will often just not care anymore. So next time they'll make a C or a D and won't care.
Parents showing kids they recognize their efforts and achievements show their kids those things are important.
I do know parents who take their kids to school every day before they go to work. If their child has anything going on in the opening exercises they are sitting there cheering their kids on. They just go in late or take the morning off. They put those things first.
