Everyone has covered most of what I would say, but just wanted to add a couple of things (by the way Robyn, I'm in the States, and I was going to mention Lansinoh as well - it's fabulous!! )great for chapped lips too - lol!):
-First-Give yourself a huge pat on the back for even thinking about giving this beautiful gift to you and your baby!!
Nobody in my family breastfed, but there is so much support through forums like these and LLL.
It is different for every woman, but just remember that BOTH of you are learning a new skill, respect that time it will take to feel each other out.
Please know that cetain things like a C-Section can make it a little harder in the beginning, but it absolutely gets better and easier - I didn't know that and thought there was something wrong w/ME but my body was just recovering.
Even if you are too shy or nervous about asking questions outright - lurk on boards like these!!
I did, and it helped tremdously!
Take time to enjoy it - even if it's just one feeding your lo is lucky enough to get from you - it's a lovely moment.
Set small goals. My overall goal was(is) to breastfeed for a year - but obstacles do come up and I had to redefine my goals! My first goal was to just get colostrum into my lo. Then I took it feed by feed until I thought I could make it to 6 weeks. Then another week and so on (at 7mo and going strong!). If I looked too far down the line it was too overwhelming.
Is is worth it? If you are able to do it you will probably find that it is worth more than words can describe. I wish you the best while continuing your breastfeeding research. No matter what you choose to do, or what you have to do, the fact that you considered this an option is lovely.
