hey parents, if you're ever considering teasing your children, consider this advice:
don't
It's something that is very easy to do too much. My daughter is like me, very touch-sensitive and jumpy with it. So no surprise tickling for either of us, unless you want an involuntary elbow in the face.
Your point on bullying is spot on. You're already in a position of complete power over your kid, you need to be the one person they can rely on absolutely and without any doubt.
