Starting to spazz a lil bit

Well I'm just shy of 8 weeks til lil miss Bella makes her arrival. I decided early on that I wanted to breastfeed her. I wish I would have done it with Dakota, but now I"m becoming extremely intimidated by it. I know I will be pumping a majority of the time because I will have to go back to work. I'm just nervous that I won't be able to produce the milk she will need to grow. So just a forewarning that y'all might see a few frustrated posts after she comes. Hopefully I can get some help from other mama's that breastfed. I just don't want this to be something that I fail at.
