if i were ever tasked to teach a class on parenting it would be short. i would walk into the classroom and write the following bullets on the chalkboard:

1. put any material things you really care about in long-term storage. if you feel you can't live without them, visit them on the weekends.
2. if you feel yourself getting really angry, leave the house until you are no longer really angry. good things/decisions/memories never happen when people are really angry.
3. learn to breath through your mouth, exclusively. this doesn't become hyper vital until your child stops nursing and starts eating the same things you eat. but start practicing the skill early. when it becomes relevant, you'll be glad you did.

once you've read and understand the above points, you are free to leave. oh, and one last thing, your children will one day understand more about the world at hand than yourself, respect them accordingly.
