Emotional intelligence varies, though. My two-year-old is remarkably observant and has stopped to ask Mommy or Daddy “You okay?” more than once when one of us was letting our distress show through.
Me, as an autistic pre-schooler? Fuck no, in retrospective I was my parents’ worst nightmare until I started being able to piece together social cues and link them to cause and effect. I don’t think I started figuring that shit out well into elementary school.
