I am about to be a father. The Good Greatsby has wonderful advice for teaching kids with rhyme:

Flirting:

Don’t blow off a lady when you learn she has a mister; relax, play it cool, she might have a sister.

Sleep safety:

Check under the bed before you count sheep, you never know where monsters may creep.

Vampire peer pressure:

Sucking blood makes you a dud.

Fashion:

No man is a fox wearing black shoes with white socks.

You should, of course, read the whole thing.
