I feel and research has shown that breast feeding babies is the most healthy way to feed babies. (An aside: There are some moms that choose not to breast feed or some who are not able to, for work or insufficient milk supply, and that is just fine. Please don't let anyone make you feel bad for your choice. I feel most parents are doing the best they can and making decisions they feel are best for their children. Don't fall into the judgment trap. I love this quote from Mother Teresa, "If you judge people, you don't have time to love them.")Okay, for first time moms preparing to breast feed is difficult to understand, because you don't know what it feels like, what it should feel like, what it shouldn't feel like, if your baby is getting enough, and so on. I am going to do my best to explain what it has been like for me. Your experience may be totally different but at least you may get an idea.
I have heard many people say that it is important to nurse baby right away in order to get that "connection." I do think this is important but my second baby was taken away quickly for testing and I wasn't able nurse for the first time until 3 hours later. (I was a little upset about that but at least they made sure he was okay.) And you know what it was okay and we were still able to get that connection.
For your first baby, a nurse should help your baby latch on the first time. It will probably be awkward. For me I had one arm trying to hold the baby in the "right" but unfamiliar position, one hand trying to hold my breast up to his mouth and then the nurse's two hands trying to get a very small mouth around a small nipple. There was a point were it felt like he was latched on okay but the nurse said that wasn't right, and then she said the baby was latched on right but it didn't feel comfortable.
This is what worked for me... The only position I like and use is the cross-cradle hold.

The baby sort of lies on my forearm and my hand is behind his head and neck.
I really like this hold because I feel like I can move the head where I feel most comfortable. In the cradle hold I feel like the babies head moves around too much and I can't control it. But you really just have to find what works for you. So there are 4 main ways to hold the baby,
the Cross-Cradle hold,
Cradle Hold,

Football Hold,

and Side-lying Hold.

The Cross-Cradle hold has worked for me and that is what I use. Find what works for you.
When the baby latches on, his lips should look like fish lips or like he was saying "Ooo." The lips should but rolled out around the areola (or the dark circle part of the breast.) The baby should not latch on only to the nipple and the more area of the areola the baby latches on to the less it will hurt. In my case, my babies latch on and when the nurse is looking, it seems like the baby is only latched on to the nipple, but part of my areola is in his mouth. To the nurse it didn't look right but it felt fine. But do be careful because sometimes it feels okay but later you realize the baby wasn't latched on all the way because it is really tender or you may even get a blister. Please do whatever you can to not get a blister, because sometimes you have to nurse through the pain because your breast being so full is even more painful.
Since it is the first time nursing, the nipples will be tender. For me it was at least 2 weeks. I know that sounds a long time but it gets less and less tender. The lubricating nursing ointments are awesome, use them!!!
Even later in nursing some moms said that it hurt every time they latched on. For my first baby it was usually at the end of a feeding when I felt like he was sucking harder to get more out. But with my send and third babies I had little or no pain at all. I know the first isn't always easy but it will get better.
So, when your baby is first born and for the first 2-3 days your breasts make colostrum, a yellow, watery pre-milk—that your breasts make for the first few days after birth helps your newborn's digestive system grow and function. Then your milk will "come in." For each of my babies this was an uncomfortable and even painful adjustment period where my body was figuring out how much milk to produce for the baby. My breast get uncomfortably big and are painful to the touch. I instinctively want to "express" or pump my milk to relieve the pressure, but the relief is only temporary, until the breast find the balance. And if you pump too much it will only take longer to find the balance. When your baby has a growth spurt, gets sick, starts teething or sleeps through the night, the balance of your milk will change and it can get uncomfortable again. I have heard that chilled iceberg lettuce placed directly on the skin can help, but I haven't tried that.
My cousin said that her baby was more fussy and seemed more hungry that normal and a friend told her that the baby was probably going through a growth spurt and probably did need to be fed more. My cousin said that it was just helpful to know that the baby just needed a little more food. In general babies growth spurts happen in the first 7-10 days, 3-6 weeks, and then around 3, 6 and 9 months. If you have an idea when to look for these things it is really helpful.
Teething can also disrupt, well everything, but it definitely can change eating. And even if you don't feel teeth doesn't mean he's not teething. Teeth move up and back in and up and back in. So painful for the baby. I have said I think it's good that the babies don't remember the first year or so because of all the growing pains, learning to breath, eat, crawl, walk etc. etc!
Ok, now this is a little more difficult to explain. It's called the "let down." It's when your hormones trigger your milk ducts to release the milk. I have had it feel lots of different ways, most common for me is a kind tingle or "movement" sort of in the middle of the breast. Other times it has felt like pins and needles (almost or a little bit painful but only for a second), a sort of "pulling" feeling coming from the side of the breast sort of under the arm. Those are the best descriptions I can come up with, but listen and pay attention to your body.
I used to use breast pads all the time until a friend told me that when she felt her "let down" she would just fold her arms across her chest and put pressure on the nipples and it would stop the leaking. But be careful because if you just put pressure on the breasts, it will leak even faster. I told a sister-in-law to use breast pads for at least the first month but I am changing my mind. When at home, try to learn what your "let down" feels like and learn how to stop the leaking. (Breast pads can be expensive.) If you go out and you feel you might leak by all means where breast pads, but the quicker you learn the less pads you have to buy.
My mom told me that when my milk "lets down" it can squirt out. I didn't really believe her. But when I was in the shower and the warm water was on me, my milk "let down" and there really was a couple streams of milk coming out! And if you ever pump you will see that milk comes out in 2-7 different streams during each suction. It's crazy but definitely helpful for infants who are still learning how to suck and swallow. I really think the woman body is amazing!
Now this next part is a little strange. It is something that caught me off guard and felt weird. With my first baby sometimes when I would nurse I felt weird, almost as if I was getting "turned on" while I was nursing. It really weirded me out, so I went to the internet and found that other moms had felt the same thing. Nursing releases hormones that helps the uterus the contract and go back down to normal size, but those are also the same hormones that are felt during intimacy. It was so weird for me that I wouldn't allow any touching of my breasts while I was being intimate with my husband (sorry if this is too much information for those who know me, but I want to be open and honest.) It was weird to feel that during intimacy and then "turn it off" while I was nursing. But with my second and third babies I was able to distinguish the feelings better and it wasn't so weird.
I have a few more things to talk about but that will be in Nursing or Breast Feeding Part II
