My toddler wont stop smelling
She smells all the time. I tried to bath her, reset, change her clothes and diaper. I bathed her in a bathtub, in the Sulani sea... I made her go potty, use the diaper and then change it. NOTHING wor...
This often happen if the Sim grows from infant to toddler while having a smelly diaper.
You can cheat remove the trait that's left over (don't know the name though would need to check the toddler for that) or you can try aging them down in CAS and then remove the diaper as infant and then age up again.
Try on a backup of your save game.
