Breast Feeding Q&A

I am currently 36 weeks pregnant and have just began reevaluating the possibility of trying to breastfeed my son...When I had my first baby 4 years ago, I knew I would be having surgery within a week, so I didn't even try, so I was just going to formula feed again. However, I recently discovered that among the many other benefits, breastfeeding helps boost immune system, reduce allergies, and ear infections (all things that my almost 4 year old has struggled with most of his life). However, no one in my immediate family has ever breastfed and I know pretty much nothing...Please direct me towards resources to find out more information.
