10 changes/day is a lot, even for a newborn. This number quickly drops to perhaps 4-6 per day, and continues to drop towards 1 year of life. As others have mentioned, it would not be uncommon to get to around 3 per day for a 1-3 year old. I also speak from experience with my own kids and would back that up as true. Therefore, the cost of diapers is probably quite a bit less than $1000/year even in the worst case. We've also invested in decent reusable cloth diapers. To buy "enough" of them so we aren't running out or doing laundry on a small set of them every few hours, we spent around $600 or $700 for a good bunch of them. These are reusable for years, and even across children. There's even a decent resale market for them if you can believe it. By far they are the cheapest means of diapering children, especially multiple children over time. However, the downside is quite an increased amount of laundry logistics. And, in some cases, it doesn't obviate the need for disposable diapers. For example, if you're going somewhere for the whole day, it might be easier to use disposables since you don't have to carry around soiled cloth diapers. Or if the kids visit other family... sometimes just simpler to rely on disposables.
