Spent all of today (until now) unplugged which is very unusual for me. But nice. Just catching up on this thread... and a lot of good points!

Interestingly, DS today, unprompted says "Dad, remember when we didn't do math for a long, long time? Well, Biology came into my brain, and Math went away. But now, Math is coming home."

That didn't stop some 30-off minutes of "Biology" questions later in the day, but he is showing interest in math again.
