How many diapers should I buy?

Generally, you'll want enough diapers to allow you to wash every 2-3 days. You don't want to let dirties sit longer than that anyway or you'll have smelly diapers that won't come clean and can possibly mold. The average is about 8 diapers per day, totalling a minimum of 24 diapers. It's a good idea to go with 36 just to be safe. Of course if you're using prefolds/fitteds and covers, you'll need that many diapers and about 6 covers, since the covers can be reused until they are messy or you feel they need to be washed. If it's AIOs, that many diapers total. But...I dare you to just buy that many! As soon as you see all the cute diapers out there, you'll want more!

Remember, a newborn will need to be changed much more often so be sure to get at least 36 or more. Toddlers may need to be changed less often.

And, once you get to the potty training stage, there are Cloth training pants available too!
