You might consider creating an alternative reminder in the form of a big, clunky bracelet. I used to have a truck that didn’t kill the headlights when the key turned off, and I drained my battery a dozen times until I put a big, stupid-looking, dangly bracelet on the headlight knob and then put it on my wrist every time I turned on the headlights. Never drained the battery again. When I get to the point of going anywhere routine with Baby Isaac (I work from home now), I’m going to put an equally big, stupid bracelet on his carseat. Put baby in carseat, put bracelet on me, never forget baby.
