You don't listen, you think it can't be that hard.
It is.
It's been eight weeks since our beautiful daughter was born: those have been the hardest eight weeks of my life, and I'm the father! I am so grateful I'm male...
You get used to it, though. Things settle down, but don't return to the previous normality. I doubt they ever will. Broken sleep becomes a habit you learn to live with.
Eight weeks - we're now glad we had our baby. At three weeks, we thought we'd made a terrible mistake, and our experience has been relatively uneventful.
My advice: prepare for the toughest challenge you'll face, emotionally, physically and mentally - including computer technical support lines.
