Here in a couple of weeks when I parent-proof all three of them, the dimes will come out. It’s pretty motivating when they get to put a dime on top of each fact instead of just a sticker. (And they can buy lots of M&Ms with ~$16.)
I only have one child who will be officially memory-master proofing all the way through the director proof. With the other two, I still go through the process of proofing them as a parent - they're my little Memory Masters in Training. To know a bit more about what a Memory Master is, click here (though that post was written last year!).
