Is it unusual that not only do I not let my kids have unsupervised internet access, I take their electronic every night

To a certain extent. You have to let them have some control and freedom, otherwise once they're completely alone with it, its not going to be good. Gradually give them more freedom overtime.

Sounds like a candidate for parent of the year to me.

It's better for kids to adjust to the real world. Can't hide behind a screen all day!

i know lots of parents that do that.

I am dad and they are 13 and 15

If they are 18+ then it’s weird. Otherwise you’re being a great mom!
