When you see an interest crop up in one of your children, find the resources needed for them to pursue it.
Make it a part of their “curriculum” and let them pursue what sparks their interest. Maybe they’ll be immensely interested in something for a while and then lose interest and go on to something else as some of my kids did. That’s okay. Their interests will be broadened that way.
Never feel like you have to stick to the traditional school subjects.
Life is so much more varied than the average school curriculum.
