Diapers are something that your baby will probably wear daily for about three years. Think of how many diapers end up in a landfill from just one baby! This is an area where parents can make a huge impact on their baby's environmental impact.
There are a number of diaper products on the market that are biodegradable. Some even say they can be composted. I'm sure this is true but before you start throwing diapers in your compost make sure you have a large, developed compost pile. If your compost is 90% diapers they will take a very long time to decompose.
Since you will go through thousands of diapers over the years this is a great way to start having a green baby. Watch for future posts on green parenting.
