They go through about 10 a day...stock up!
Google "how many diapers do I need". There is a great blog that should be #1 result. It discusses how many you will need and how much you should pay for them. You can always exchange sizes, but you'll mostly want to stock up on size 1 first.
No pun intended but a poop load :)
I agree with the other ladies. Definitely stock up! Cause you'll have those moments when you go to change a dirty diaper and then a couple seconds later they poop. Lol My kids always did that!
For my baby registry we scanned at least 70 box of pampers then like 30 small bags of them lol ... and we have at least 3 boxes in the closet now
