How much time do you allow your DC to pursue their own interest? DS loves to pursue his own interest for hours at a time. One of the reasons we decided to homeschool was so he could have the time to pursue those interests down whichever rabbit hole he wanted. But I'm beginning to get a little worried about HOW much time is considered...healthy.

DS is a mathy kid. He converts everything to numbers. He dreams in numbers. He currently likes to work in Excel where he can look at number trends, test out formulas, graph data sets (latest pursuits), etc. He's self taught fraction to decimal conversions, division, multiplication, squares, square roots, averages, etc. The list goes on and on. On the one hand, yay! Because he explores and really learns to understand, so "gets" everything he is learning. On the other hand, he's on the computer experimenting for hours on end. I was ok with 2 hours to pursue an area of interest. I am a bit nervous with 6.

He is good about taking breaks to eat, ask questions, run errands, help with laundry, etc. I also don't want to discourage his pursuits.

Any ideas?
