Hi Ami, welcome to the forum.
It sounds like you and baby are doing very well, but you are still unsure if you are correctly breastfeeding your baby by switching breasts each time.
From what I have learned, the underlying principle is to empty each breast before offering the other one. Here's an except of an article that helps to explain why this is important (from http://www.wiessinger.baka.com/bfing...s/3course.html)
Your between-nursings "seeped" milk is a rather lowfat milk. When your baby nurses, she first drinks this "soup course". But the action of her nursing begins to draw down a higher and higher fat milk. Most of what she gets from that breast is a medium-fat "main course," but near the end, when she isn't swallowing very often, she gets the highest fat milk of all - like the small, high-fat dessert after your own meal. If she nurses again soon after, the fat tends to be mixed all through the milk. As the time between nursings gets longer, the difference between low fat and high fat milk becomes greater and greater.
If you follow the old, rigid advice to wait a certain length of time and then nurse on both sides, taking her off Side One in order to give her Side Two, you'll be giving your baby two "soup courses" and may leave her too full for "dessert". She'll be full - but not necessarily happy. All that lower fat milk without enough high-fat milk can upset her intestines, making her gassy and colicky.
As for the paci, I personally didn't use it because my baby didn't like it. But I have heard that offering it too early on might cause nipple confusion.
Hope this has helped.
