you have gotten great advice already...just want to add in my few pieces of experience.
it may be way easier than the first time.
it may be really painful at the beginning, or it may not hurt at all.
you may need to feed every hour at times, or your babe could go up to 3- 4 hrs at a time at others. the guideline of every two hours and so on comes with the schedule of a ff babe. same with amounts.
you will never know exactly how much your little one is getting when he/she nurses, but as long as there is good output there must be good input.

the pump is definitely not as good as the babe at getting that milk supply up. so nurse away.
get help from a lc if you are having issues right from the beginning...but then look to your instinct and your child. we needed the help immensely at the beginning, but a few weeks in, once we got on a bit of a roll and dd was finally nursing properly we let her guide us and worked with our own instincts. and that worked well too.
i guess the main thing i'm tryin gto get at is that it likely won't be the same experience as it was with your first.

and that is ok!
get a really good nursing bra or tank to wear. it'll make things much more comfy for you. i loved my Bravado Designs bras and tanks (
Bravado! Designs ) great fit, comfy, cute and really excellent function and quality. worth every dime.
you can do this!!!!! and it is worth every bit of effort...
