Heles7 gave some fantastic advice and I know she went through the mill with her LO....
I've known other bfing mums who swear by nipple shields. I personally never got on with them, but some mothers do find that they are a relief.
I used Lanoish as the other girls have said. Also when I had salt baths for my stitches, I made sure my nipples got a soak... If anything it just felt nice.
I breastfed both my girls but my first was definitely more of a challenge. Bfing is a skill...like riding a bike..only this time you're riding a tandem bike and both you and your LO have to learn the skill. I think that the first 6 weeks are the hardest because you are also recovering from birth in that time, so you have exhaustion to factor in. Try not to be tempted to introduce a bottle just for a break because it will drop your milk supply and you will find that its difficult to drop those formula feeds and with many bfing mothers, it signifies the beginning of the end of their bfing.
I was lucky in the sense that I didn't feel the need to go out, I enjoy being at home, so staying in with a baby attached to my boob constantly was more like a nice holiday...
But yer...bfing is painful and uncomfortable, especially in the first weeks but it is worth it in my opinion and you are doing so well. Try not to focus on the big picture, ie you should bf'd exclusively until 6 months, say to yourself, I will continue breastfeeding until my LO is 4 weeks old. If you get there... say I'll go to 6 weeks then...if you get there say 8 weeks and so on...and if you get to one of your goal posts and decide bfing is no longer for you, you won't feel so disappointed because you did exactly what you said you were going to do... you reach your goal
