cloth diapering!

My husband and I are pregnant with our second baby. Definitely an unexpected pregnancy, and I was considering cloth diapering to save money. I have so many questions! Like how many of each size is a good amount and how do you clean them. (like any special tricks or suggestions to make it easier.) Do they really save money when you include the extra washing and drying you'll be doing? I haven't made up my mind on it clearly, but any info I can get is welcome! 😊
