So I feel like this is a bit of what unschooling allows.  Each child (and parent) can become an expert on whatever they are currently interested in.  Often outsiders (those not actively working with kids) wonder how they will learn all the school subjects when focusing on one topic.  But I have found that no matter the subject kids go deep into subjects are introduced, explored, and mastered.  These subjects include math, writing, reading, spelling, science, history, but not in the way a textbook spoon feeds them.  

Just something to ponder, notice, and observe as you take the journey with your family on this unschooling path.
