Nipple Piercing Questions

I have a few questions for you ladies with nipple piercings. 1) About how long did they take to heal and how long do they stay sore after piercing? 2) If you've had kids since, did the piercing affect your ability to breast feed? 3) finally, are you happy with the result? Edit: it should be noted that I'm a D and can't fall asleep if I'm not on my stomach. So if you have larger breasts or are a stomach sleeper has that been a problem?
