That elevator pit is no joke, way too easy to get hurt down there. A magnet was smart for the wrench, but you really need to kill the power first. My uncle works building maintenance and says people forget the pit is a full machine room. It's clever, but next time maybe just call the super and avoid the risk entirely.

Finger stretches are a good idea. My hands cramp up sometimes too, and I fix small things for a living. Makes me feel like my hands are older than the rest of me.

Besides @the_blake's headphone tip, changing feeding times could align your baby's sleep with work hours.
