Another one here who tends to think that ultimately it's all up to the baby.
My two were like night and day to breastfeed, yet there wasn't much I did differently. One just came out knowing exactly what he was doing from day 1, the other needed a lot of help.
That's not saying it's totally out of your hands though, do all you can to prepare and the rest I think you just have to take as it comes. Oh and defnintely go the Lansinoh...I'm just rediscovering the joys of that stuff atm since DS popped his first tooth ouch!
