So my fiancé and I agreed that every payday we get we're going to start buying a thing of diapers. We already know what brand we're going to be using, but I was curious as to what sizes we should buy and how many boxes we should buy as well. I'm not going to buy any newborn size diapers until I know for a fact that the baby will either fit them or not. I'm going to start out by buying 0-3 months, but how many boxes do you think I should buy? And how many boxes of 3-6 months should we buy as well?
