New to cloth

Lexus • Mommy of 3💖💖💙

I have 3 kids, ages 2,1, and 2 months. We’re going to start using cloth to save money and I am lost. Can the 1 and 2 month old share diapers if they’re one size? We’re planning on using Alva baby pockets but how do I prep, wash, store them when dirty? Just starting out so any help or advice is appreciated
