Bridget I'm sure you will manage it this time - To me it seems you were nearly there last time - I always think if you can get through the first week then you're ok!
Demand help! With ds1 my mum (I was still living at home) was dead against me bfeeding, and he wouldn't latch properly and kept sticking out his tounge. i knew if I went home unsure of how to do it I would end up stopping, so I stayed in hosp overnight and rang for help to get him on properly every time he needed feeding, and then by the morning we were fine.
Its not an easy, natural thing for everyone - It hurts to begin with! it's tiring and then there is this massive pressure put on women too 
However
Im very lazy
and couldn't be doing with faffing over bottles, making them, washing them sterilising them, remembering to take them with you etc etc etc
Whatever way we feed our babies, as long as they are fed then they will be happy! and if they are happy you are doing a good job
