children dying/ghost babies/kids' tombstones

Sounds like a really cool idea. For kid deaths in my gameplay, I've only had success with fires and using MCCC. With MCCC you can kill any age sim with anything and they will die immediately. There's also this one R-rated mod that I don't think we're supposed to talk about on here but I'll mention it anyways: Random Violence. You can definitely do some interesting things with that. There's also a tragedy mod you can use to get your sim kidnapped/murdered/etc (Clare Siobhan did a showcase during one of her let's plays and it was out of control). I will say that I've tested each of these mods and they're a bit buggy and can cause all the sims in your world to go crazy fast but I think if you use Random Violence to kill the kid, exit the game, remove the mod, and then go back in, the kid will still be dead from an unknown cause. That's what happened to the sims that were killed in my save with the mod installed and then when I removed them it just said "Died by ___". It can add a bit of mystery to your game for sure.

When you finish your save, I'd appreciate if you can post a download link to this thread so I can find it easily and play with it!
