It didn't cross your mind, but it did cross the mind of others.
I worried. While this thread has found 2-3 clips of Nick barking at his kids a bit, there are another 5 or so in which he had to interrupt his stream to tend to the daughter (the one who tested positive) with night terrors.
(Incidentally, this is when I started worrying about Kayla as a mother. Nick was
working and, stereotypically, it's the mother who calms a terrified child. Also, in my experience this calming usually takes 5-10 min., a proper snuggle, etc. Nick would be back within 2 minutes. At the time, I pondered if he just fired up her iPad.)
The confusion (Captain Manning's and others) may be because Nick did a fairly good job keeping his kids private. Until around the Worst Day and Hedonism II, we knew next to nothing about his kids' personalities, save the favored and difficult daughter. I don't recall him
ever expressing animosity to any individual kid. He just whined about driving them everywhere. (In fact, it's concerning how much other streamers share about their kids in comparison.)
Anyway, I always assumed Nick's karma would come as his kids got older. I remember him declaring "Babies LOVE me!" All his kids were developing agency. The Kermit voice that his kids (and fans) loved so much didn't cut it anymore. My theory: He was experiencing pushback from his audience
and inside his home.
