Cloth diapers

ttc-5

So, this will be our fifth child, and I accidentally quit my job-hormones, so I was thinking to save money, cloth diapers would be the way to go. I have a few questions that other moms may have answers to... How many do I buy? Do you have to use a special soap to clean? How do you travel with it? Stupid questions, but I really don’t know. The more and more I think about it, the more I think cloth diapers are the way to go. Thank you guys for any info
