I would relax and enjoy my children a little more. I was crazy about making sure that I was not creating any "gaps" in their learning. Had to fit it all in!
My children have both grown and gone now. We home educated them for fourteen years, and then they grew up and went to college. My oldest daughter is out of college, married with a responsible job, a hubby, their first house, and their first child. My younger daughter is in her senior year of college. Both of them have consistently been honors students. Both of them have very high moral values. Both of them are people that any mother would be proud to call her own. In college, they attracted a lot of attention from their professors because they were very creative, intelligent, and hard-working. They got faculty selected scholarship opportunities out of the blue. My youngest one just picked up another one last week, that she did not even apply for.
I tried lots of different curriculums. My personal favorites were Saxon Math and Sonlight Books. The first because of an easy to use format, the second because of the rich, literature based instruction.
Enjoy them while you have them. They are grown and gone way too soon. I am so glad that we homeschooled. We were knit together as a family and the ties are still strong.
