I started writing this as a note on my profile in FB but figure it should go here as well.
Rule no. 1
Admit when you're wrong and apologize to your child when it's called
for. Don't let pride or ego get in the way. When you send you child to
bed crying it had better be for the right reasons and not for the wrong
ones. Otherwise you may one day wake up and realize just how much you
child can come to resent you.
Rule no. 2
Make the rules and and don't break them, but be flexible enough to bend when the situation needs it.
Rule no. 3
Do as I say and not as I do. Bullshit. If you can't back up your words
with actions, don't speak. Your child has a damned good memory and will
remember what you teach them, good or bad.
Rule no. 4
You can be your child's best friend, but don't give up being their parent first.
Rule no. 5
When your child is the one to act like a grown up and remind the parent to be a grown up then you know the roles have been reversed and you as a parent have lost control. If you want to keep the authoritarian role as parent you need to remember to act like a grown up.
Rule no. 6
Don't let your child keep nagging you to the point of snapping. Tell them in no uncertain terms and a firm tone of voice to stop or they lose whatever it is they want.
