Does your child sob when you leave them? Do you reassure them that you'll "be right back"? Are they still upset?
As it turns out rational thinking is a higher brain function and when kids are heart-broken at your departure this function is unavailable to them.
Empathy is your friend in this instance and every other instance of upset! "You're sad I'm leaving huh? Darn. That doesn't feel good." Some time and a good snuggle will send the empathy home.
You'll still walk out the door and you'll leave a much better-feeling child behind.
