Step two: get pregnant
Step three: live in an area that is not hostile to breasts that are functional
Step four: get to know a few people who have breastfed babies and think it is a good thing and read The Womanly Art of Breastfeeding Edition 8 or earlier.
Step five: have the baby
Step six: nurse the baby right away
Step seven: call on of the people recommended in step three if there any breastfeeding glitches and they will help you resolve them
Step eight: relax, enjoy the moment and remember that for your entire nursing career this may well be the only time you get to sit down
If God had intended us to not relax and enjoy our babies, he would have made the human breast detachable.
