Bet your bottom dollar they are! We've compared the ongoing costs of purchasing and laundering reusable cloth nappies and compared that to the expense of buying disposable nappies in the years from birth to toilet training. And it's true! Even when accounting for the costs of purchasing cloth, the water and electricity involved in laundering your stash, and even the detergent needed to wash, cloth nappies consistently save families $1000+ a year, with bigger savings for subsequent babies.
