I second all that's been said, especially about reading as much as you can. The ABA's "Breastfeeding...naturally" is fantastic. I don't mean to brag but I apparently had such good "technique" when in hospital that one midwife asked if this was really the first time I'd breast fed.

I remember with my first bub I was a sleep deprived mess by the time I needed help, and I could barely think straight long enough to even sit down with the phonebook and try to find the numbers of the ABA or look for an LC.
I can sooooo relate to this! As prepared as I was for BF I hadn't read how to use my steriliser for expressing EBM and I swear it took me about 2 months to get the mental energy to read the instructions and sterilise for the first time. I kid you not - there is a lot going on in your life with a new bub and the last thing you will want to do is learn a whole new concept (which BF is for many) when you are tired/emotional. There is so much information and support out there about how BF works and IMO you will be much kinder to yourself if you start learning now.

But that said an important thing to remember is that BF is a RELATIONSHIP! It is not one sided - you need to get to know your bub and that takes time. Nothing is perfect from the start, some babies are lazy latchers, your milk might be fast or slow, whatever. Give you and your baby plenty of time to get acquainted, surround yourself with fore-knowledge and options for support and trust your body and baby.
