The Sims 4 MOD: Bedwetting for everyone (Pets ready)

This script simulates the effects of bedwetting and incontinence in Sims 4. Diapers included!

Ready for Pets Patch (7th Nov 2017)

In this current state of beta, both traits can be acquired by using 100 reward points in the reward store.
Sims without one of the 2 traits will not wear diapers or act different in any way.
You can acquire both traits at once that way, but it does not make your sim more incontinent, just because he is a bedwetter too.


  • The bedwetter trait stops sims from waking up at night to go to the toilet. But more so wetting the bed. (Ages child and up)
  • Toddlers are all bedwetters, even if potty trained to lvl 3. They will never wake up at night because they need to go to the potty. If they are asleep they wet there diapers.
  • The incontinence trait stopps the sim from realizing that he has to go to the toilet. Incontinent sims will have diapers equipped all the time by default (like toddlers).
  • The state, if a sim has diapers equipped or not, is traced. Currently you can not equip a diaper by choise. Bedwetter will equip one while sleeping and incontinent sims always.
  • Sleep and nap did not allow for the execution of other functions (like using diaper or wetting the bed). Function added as exception.
  • In case of usage of diaper while unsupported functions are running, the usage of diaper will wait for the end of the unsupported function before execution. Usage of diaper can not be cancelt.
  • If (because of bedwetter trait) an accident happens over night, the sim will have a diaper equipped until he changes (out of) diaper.
  • Bigger sims (child+) can change theire diaper by using a dresser.
  • Taking a shower or bathing (any type) changes diaper too, but only after the shower/bath is finished. By doing so, slows down cleaning process depending on how dirty the diaper is. This represents the additional time needed to clean up.

Featurs in development:

  • Sims need to put on diapers and can do so even if they are not incontinent or bedwetters.
  • EVERY Sim will require potty training. Every use of the toilet will reinforce the potty-training, time and more so using diapers/peeing pants works against that.
  • Very young and very old sims will have a more difficult time having no accidents. Accidents can happen at random with low potty training skill.
  • Different traits and rewards can make potty training more or less difficult. Some sims may have difficult with dry beds at young age, while growing out of it later.
  • Sims will try to equip diapers autonomous, but have no longer one quipped by default if a trait applies. This can lead to accidents without one.
  • Putting them on or changing diapers will always be embarrassing. Sims with the shameless-trait do not suffer from this.
  • Autonomous change of diapers, not only by taking a bath/shower.
  • Urine and poop will be 2 different things and be handled differently.
  • Diapers will keep track of content and its age. Not changing diapers can lead to rashes or infections, also for toddlers. (The current rashes are just to easy to fix, just change the diaper…)
  • Beds and chairs can get messy if a sim does not has a diaper equipped and has a “bladder failure” (for whatever reason). He will no longer just stand up and play the animation, following a puddle on the floor.


– Because of “looping_content”-animation, “toddler_UseDiaper” or “toddler_UseDiaper_Continuation” can not trigger, and because of this diapers not used while one of the following functions are running:
bed_Nap, chair_Nap, ToddlerhighChair_Nap, sofa_Nap, sofa_Nap_Toddler, chair_Nap_Toddler, napOnGround

As you can see from this list, even nap functions of toddlers are affected, even in the original sims 4 version (without any mods).
I could not fix the functions for toddler, but “bed_Nap”, “sofa_Nap” and “chair_Nap” work just fine now.
If someone knows about a fix, please share!
– McCmdCenter was incompatible to my mod. That was because of a xml used for debuging only. Should now work fine.
– I added interfaces to python-functions into the xml. They do nothing in this version (short generating a log if you activate this). Will be used for messages for the player in case of accidents
– “bed_Sleep_Butler” and “coffin_Sleep” now support nighttime accidents too. “Tent_Sleep” can not because of the same problem with “looping_content”-animations. The only solution would be to remove the animation for now…
– Cleanup of translation files, should be now the last problem involving McCmdCenter. In 0.23 McCmdCenter was working, but some translations where missing because of the overwrite by my translation nodes.
– Any type of shower or bath action is now supported for changing diaper, but any of the 2 actions have to end on there own. Use the dresser if you only want to change the diaper.

– New log system that now works even if the program is packed. Because of stupidly bad error reporting by sims 4, 3:30 hours debuging and 18 restarts of sims 4 are included.
– Config file writer that can save/load configurations. Config file can be changed by program or user to change behaviour of this mod (currently no working settings, even if it looks like it)
– Compatibility patch for version Changes for Pets expansion pack changed the way “species” is handled.

In general this mod will clash will all other mods modifying one or more xml i modified too.
“motive_Bladder”, “sim_BladderDistress”, “bed_sleep” or “shower_TakeShower” for example.

I also overwrite “whims.whims_tracker”, so all mods modifying/adding rewards will probably not be compatible.
If you implement other mods with rewards after this mod and you can not find my traits any longer, you can also add them by console command.
