When should you start potty training your children? Most parents don't imagine starting until the ages of 3 or 4, just as my husband did. However, with a little research on the subject, people will come across the subject of elimination communication, or EC. This is my journey navigating the world of elimination communication, and some advice on how you too can practice this with your children.My husband thought I was crazy at first for wanting to try this, but after the success we had with our first two, he was the one asking if we can start our third baby the first week after birth.
