(I also did this for Month One and Month Two.)
I don't do it on purpose (that is, I change "when he needs it," not on a schedule), but we use almost exactly the same number of diapers per day: it's almost always six diapers. For "cost per month" purposes I like to round that up to 200 diapers per month--just to be on the generous side. So in months three and four (i.e., from the day he turned 2 months old until the day he turned 4 months old), we'll estimate that Henry used 400 diapers.
I buy Target brand diapers, and Henry is still in size 1 (skinny butt). I can buy a package of 112 size 1 diapers for $10.60.
Math time! Price of $10.60 divided by 112 diapers in the package, is .0946 cents per diaper--approximately 9 and 1/2 cents each. Multiply the per-diaper cost times the 400 diapers used in two months, and we get $37.86 for two months of diapers--or $18.93 per month to put this particular baby in disposables.
And we didn't spend that much. We used more like 360 diapers, as I mentioned, and I saved about $4 with a store coupon and a freak clearance. With those things figured in, we spent closer to $15 per month.
