Fairly certain it’s just prolonged, extreme sleep deprivation. You can’t know if you haven’t been through it. My first required someone to be awake walking her around all night long for the first few months. I’d switch off with my wife at 3am then get up at 7 to get ready for work. For months. I actually remember the first time after she was born that I got more than 30 consecutive minutes of sleep, (maybe a week after?) because I woke up and saw the sun low and red in the sky, and legitimately did not know if was morning or evening. Turns out I had only been asleep 2 hours. I never understood the phrase “sleep like a baby.” You mean, for 20 minutes at a time then you wake up screaming?
