Breastfeeding help

I really want to breastfeed this time. I was unsuccessful with my first, he was a big boy and I don't think I produced enough. This time I'm having a girl and she will likely be small since I'll be induced at 38 weeks.
I'm mostly overwhelmed with the idea of pumping... Do I have to do that?
And I'll have a 2 year old at home with me so I'm not sure I'll be able to.
I also have very sensitive nipples so I worry they will always hurt...
I'm just not sure breastfeeding is for me but I really want to!!!!
