Feeding the baby.
I used to do a lot of posting during that time. I could cradle the Cub on one arm, the laptop in my lap, and feed him and type one-handed.
Now? when he falls asleep on my lap, he sprawls from my chest to my knees. When the heck did that happen?
I’m always up this late. I don’t have to get up for work until 10am (mid-shift) so I stay up til 2 or 3ish. Always have been a night owl! Besides, this night elf isn’t going to level itself 
I worked 12 hour nights for nearly 40 years. Old habits die hard.
