Fellow game dev parents: When did you start letting your kids play video games?

I have two kids and I am a little unsure when to introduce them to video games. On the one hand I myself started at 6 years old and have been loving games ever since. I played A LOT. And I kinda want to impart this love to my kids.

On the other hand, I want them to have a happy life and I think being social outside of digital experiences and generally being outside is a huge part of that. And I know how addicting games can be for young kids.

So I am curious: how did you deal with this?
