Possible chain reaction in family relationships?

In my current family save, the conflicts have escalated more and more over time. To put it simply: if I look away for a moment, the whole house is on fire. Negative conversations lead to new negative memories, and the relationships seem to spiral further and further out of control.

I wanted to find out where this starts. My first theory was that perhaps the Child life stage triggers these aggressive interactions, so I went back to older saves of the same family and compared their memories.

That is when I noticed something: Orlando seems to be the common factor. His relationships with several siblings develop negatively, while other siblings do not show the same pattern with each other.

Then I remembered his toddler years: Orlando absolutely hated the peekaboo interaction. Despite this, family members and even the babysitter kept autonomously playing peekaboo with him over and over again. I had already complained about this at the time.

Now I am wondering whether this could have been the starting point: repeated negative interactions during the toddler stage → negative relationship traces → later unfavorable autonomous conversations → new negative memories → increasingly severe conflicts.

Has anyone noticed anything similar? Or does anyone know whether negative experiences from early life stages can influence later autonomous relationships?
