What you do is this:
Like a flash, you SHOVE the baby with your knee/thigh, so that instead of falling off the bed onto the floor, he is vaulted several inches so that he lands on a rolling office chair adjacent to the bed.
In lifting your outside leg to push the baby, you’ve also effectively slid the laptop AWAY from the edge of the bed.
You realize afterwards that this was probably the dumbest action you could’ve taken, since you relied on a CHAIR ON WHEELS to remain steady and catch the baby.
You realize that you could not have conceived of nor coordinated that feat with any forethought.
You realize that you haven’t backed up any of your work on this fragile machine.
You realize that if you try to explain it to anyone, they’ll think you’re lying.
You are NOT making this up.
