Cloth diapering? Where to begin?

Hey ladies!! I currently have a 1yo and another LO on the way! I’m a SAHM and looking to save some money by cloth diapering. I have TONS of questions and don’t even know how to begin this journey as we used disposable diapers with our first...

•Which brand/style is the most cost efficient but yet reliable?

•How many of the diapers & inserts do I need to buy to get started?

•And last but not least, how do I even get started???? 😆

At first I do plan on using disposables when out in public until I get the hang of using cloth diapers. I really want to get started but I don’t even know how! Thanks for all the help!
