This is a common question that many people have. The cost of buying cloth diapers can be a little intimidating when you are first starting out. You must keep in mind that this is most likely a one time cost. There will be no running to the store because you are out of diapers! If you chose to still use disposables at night, you can get through without too many worries. We keep the smallest packages of disposables in the house for night, so we go through a 40 pack about every month or so.
OK…so how many do you need? With a newborn, I would suggest a minimum of 25. This will most likely not give you more than a day, day and a half at the most between washing. When they are older, I would say a minimum of 18. This again will not get you far. But it will get you started! Be prepared to do washing more frequently, and there will be more wear and tear on your diapers.
To be comfortable, minimize the wear, and have a day or two between washings, I would recommend 36 for newborns, and 25 for older babes. You can always add more of less depending on your preference, how many days you want in between washings and such.
I always want to suggest as well, that when you are starting your stash, please purchase a mix of diapers. Whether it be brands, or types (such as pockets and prefolds), this will let you know what works on your baby, and will also help minimize the costs. (It will minimize costs because you will nt be buying an entire stash of something that you don’t like!)
