I wish I had thought to create some sort of ticker that tracked the number of diapers we have changed since the girls were born. We change the girls' diapers at least at every feeding -- but there are several more in between diaper changes.
In the beginning, the girls ate every 3 hours. That would make 8 feedings and 8 diapers x 2 = 16 diapers a day. That schedule lasted about 4 months. So that's 16 diapers x 30 (days in a month) x 4 = 1,920 diapers (conservatively) in the first 4 months. That doesn't count all the times you would change them and then they would pee all over the diaper you were about to put on and now have to remove.
At about 4 months, they had dropped 2 of those bottles. So for month 4, let's say they had 6 feedings so that's 6 diapers each a day x 2 = 12 x 30 (days in a month) = 360 diapers.
Then at 5 months they dropped another. They were down to 5 bottles a day and now they still have 5 bottles a day, but we have increased the solids. So as they say in Physics, for every action there is an equal and opposite reaction. They are almost 8 months. So for 3 months, we were changing at least 10 diapers a day. Let me tell you, it's way more than that every day. Sometimes by 8 am I have changed 6. But for this exercise, let's say 10 diapers a day x 30 x 3 = 900.
Add it all up: 1,920 + 360 + 900 = 2,580 diapers. You can only imagine what our garbage people must think of us ...
