Yes, in The Sims 4, it is possible to have a baby with the Grim Reaper, but this requires a specific setup. Here's how you can do it:
Build Relationships: You need to build a high friendship and romantic relationship with the Grim Reaper. This involves flirting and sending romantic interactions until the "Try for Baby" option becomes available12.
Try for Baby: Once the relationship is strong enough, you can use the "Try for Baby" interaction with the Grim Reaper. However, some players have reported issues with this interaction not working as expected, such as not being able to confirm pregnancy5.
Special Traits: Babies born to the Grim Reaper will have the Grimborn trait and a scythe-shaped birthmark on their neck. They also have a longer life expectancy than regular Sims17.
Workarounds for Issues: If you encounter problems, some players suggest using cheats to add the Grim Reaper to your household and remove his Grim Reaper trait temporarily to enable normal interactions3. Others recommend resetting the Grim Reaper or creating a new save to resolve glitches6.
