Although cloth diapers require and upfront cost of purchasing the required amount of cloth diapers for your baby they will save money in the long run by not having to spend thousands of dollars over the time your baby is diapered.
By the time your child is potty trained you can expect to spend at least $3,000.00 on disposable diapers.
Compare that to the $500.00 or so to buy the cloth diapers and it really is cheaper even when you factor in the cost of detergent and washing them.
