cloth diapers

thoughts on cloth diapers:

are they better than disposable diapers?

do you have to buy a lot of them?

do you wash the inserts as well or dispose of them?

on Amazon I see packs of 6 cloth diapers with like 12 inserts, would I need more than 6 diapers?

any other info you can think of would be great! sorry if these are dumb questions I just dont know anybody who uses them & never personally used them for my older kids but highly interested!
