Hi Gailemma and welcome to BW!!!
I hope you will find lots of encouraging support here on the BW boards, to back up what Jess has said, this site is an extension of the books, because there is so much information in the books there is no possible way to be able to teach you everything here

I highly recommend purchasing the books and then you will have a better understanding of the kind of support you will get, we can only do so much here and its alot better to "get it from the horses mouth" so to speak, Tracy explains things a heck of a lot better than some of us can, we have only learnt from her and pass on our own experiences.
For the age of your child the recommend time they are awake is 2.5 hours, however you cant just jump to that time, you will need to do it gradually and also without feeding beforehand, there are a few techniques to doing this, all of which are layed out in greater detail in the BW books. Perhaps your sister and you can read teh books together, i know two heads are better than one in these cases!!!
