Ug Peter, you do have a lot to balance! Sibling issues are tough, but in a way the older is helping the younger to feel more 'at home' on the planet. I call it the 'at home gifted cluster.' 2nd borns who have the motto 'we try harder' is a well worn path, and hopefully your younger will stick on it.

Good for you for getting the school involved with providing some in-class accomidation for your older's group.

Chess club and Destination Imagination are great activities.

Yippee!
