Tips please!

I'm having baby #3, and am planning to make my own cloth diapers for her and some training pants for my toddler.

First-what materials work best for wicking vs absorbing?

What should i be using for the waterproof cover? Would a mattress cover be ok?

Should i make my own wipes? What should i use to make them "wet"?

Rash cream suggestions? Homemade recipes and/or store bought?

Is a diaper sprayer worth it?

Are cloth diapers ok to drip dry inside?

Scent boosters or no?

How many will i need for full-time use?
