Every year, on every one of her kids' birthday, does every mom stop and say, "I can't believe my baby is [blank] years old today!"? I swear this is me. Over the weekend, my youngest cub turned four years old. 

My first introduction to Karen Stubbs and Birds on a Wire, the mom's ministry she founded, was doing a study called Mom Core over the summer with a group of women who live nearby. It's one of Karen's most popular curriculums (and if you're a member of Right Now Media, you can watch it here, otherwise you can get it here).  I need to tell you: lesson four in Mom Core, the "Being a Student of Your Child" lesson, fundamentally changed how I parented.
