if you want to have a kid, ever, this is pretty enormously relevant
SUMMARY: for most people, the best advice will be to (1) feed your kid any time they cry (2) breastfeed (3) eat fish during pregnancy, especially last trimester (4) don't do stupid shit like smoke or eat licorice (5) get a C-section if your kid is gonna have a bigass head and get stuck in your pussy or your wife's pussy.
