If your munchkins use cloth diapers, vinegar can help keep them soft and clean.
Both my little ones are in cloth diapers, and I’ve found vinegar to be very effective in removing stains and odors.
I add the vinegar to the rinse cycle (fabric softener compartment), and it also washes out the detergent better, preventing diaper rash and making the cloth softer. My 5-month old is wearing stain-free diapers that I made for his big sister. It works on the rest of the laundry, too (but not on dark colors because it can cause them to run).
