Does anyone know what
exactly triggers this? My toddler gets this moodlet almost constantly...mostly during friendly conversation, but sometimes even when she is idle it pops up unwarranted. She apparently feels that way towards her mother, who pretty much never said anything unfriendly to begin with. She's perpetually sad because of it now, regardless of what mom says or does to make things better.

Yikes, that's brutal
I see that the toddler is independent. Maybe the mother is always helping her?
Haha, but it actually sounds normal.
@adduapina have you ever had a toddler. These reactions seem right on par for a toddler to me. I mean my kid has laid down on the floor and died because I gave her the wrong pants/plate/book/shoes. Toddlers are irrational little creatures. Perhaps they used the "why my kid is crying" posts on facebook for real life toddler inspiration.
Yeh but they don't get a lasting hurt feeling about it from what I recall of my own. Pull a funny face or wave a dinosaur at them or something and all is well again. Days later they aren't still brooding that you gave them the wrong tshirt!
Oh, I had a child like that in RL. It was so bad, I warned his Kindergarten teacher that he would likely get belligerent, if she swooped in to help him out too soon. I suggested she ask him if he would like help. He was always good about accepting help if I let him try to work it out on his own, first. I would ask before he got frustrated, just to be sure.
I have a hunch that could very well be it. Not certain how to undo such 'damage' though. Yikes. I haven't yet seen that one.

Could be jealousy. Sibling rivalry or a mixture of the two.

For me, it was after the patch.
Same. Now that I think about it, It started happening while the independent toddler was in a friendly conversation with her mom, dad, and twin sister. Everyone makes good points, maybe it is a mix?
That makes sense! I'll see if it happens with anyone else. Her sister doesn't have the trait and I haven't had any sentiment issues yet, so maybe
The direction this seems take for me, is that the toddler is seen as any other life stage which is a problem as they are clearly not.
Just for jokes, I imagine her eventually pack her bags and move out of the house, cause she is tired of her mom
Because I have NO weird experiences with Sentiments at all. Admittedly I only play a childless couple (for now) but all they do is feel happy and comfy because they're in love and close to eachother. I don't even notice that it's "on" most of the time, they're just happier than they used to be.
Of course they have matching (2 out of 3) traits, which with Sentiments provide a happy boost, plus Best Friends (also happy boost), plus Soulmates (happy boost)...
Yes I use mods, but I've never had issues with sentiments between adults though, and not even toddlers until...Alissa lmao
