I haven't released a game. I can only tell you what I've read from others. And that's best summed up as "build a community before release by being social everywhere and honing your game's appeal down to a few images and identifiable words". That isn't very helpful for you; you've read that.

Maybe contact people and sites directly that focus on family friendly content? I don't know how many games do that.

But good luck!
