I use these diapers and LOVE them. 1st, you can buy them online at Target, Amazon, Buy buy Baby, etc. The only store around me that sells them in store is Buy buy Baby.
So when you buy one it'll come with the diaper, a newborn insert and a regular insert. You stick the insert in the "pocket" inside the diaper and you're good to go! Super easy and once you have a diaper, you'll completely understand.
