My adoptive-mama friend Dr. Holly (congratulations on the fresh Ph.D.!) has a cool new blog focused only on cool, educational stuff for kids. Link heaven at Cool Stuff for Kids.
Holly is also a homeschooling mom and a clergyperson (Episcopal, I think ... is that right, Holly?). Her busy life doesn't leave a lot of time for blogging but she also blogs about her family occasionally at Coolclan.
