The moral of the lesson is to never underestimate your kids.
We have purchased g a Dora memory game ages ago. There are about 72 cards on a deck so I "assumed" (you know what they say about assuming) that g would not be able to handle remembering the full desk. I usually play the game using only about 12 cards.
This weekend she played with dad who laid out the entire set. I told him that it might be too much but he persisted.
g won 24 to 11. (one card is lost so the last pair could not be made)
Needless to say G needs to do more BrainAge.
