Hi JBDad,

Do you think there's an age component too? For instance, a lot of stuff DS6 (almost 7 now) did previously (ages 4 & 5) math topics, books, poems, tales, etc. peaked his interest then & we discussed them and he loved it. Switch to age 6 and he has almost no memory of much of it. He picks it up quickly once it's re-introduced. Guess we all are a bit that way, but usually my lapses are things I learned 30 yrs ago rather than just 2 yrs ago.
