Diaper fit forecast
Robust calculator based on peer-reviewed research
If you know me you know I have feelings about mental math. And stores are always running promotions like "spend $150 on diapers and get some special discount". Which is great when you're already spending money on diapers, but not great when you are committing to a size of diapers by the gross and you have no idea how long that size of diaper will fit your kid.
The data is out there, so I decided to put a tool together to help all of us have a bit more peace of mind.
