Please stop, you're making your brain too tired

On Thursday Linnea played with the Cuisenaire rods for an hour and then spotted the Nrich website over my shoulder, usurped my place at the computer, and spent two hours doing puzzles, sometimes with the Cuisenaire rods to help her.

She wouldn't stop. When we made her stop she played her chocolate game instead, which isn't much different, really. In total, she spent about three and a half hours doing sums and logic puzzles with shapes and patterns.

Afterwards she was tired and cranky, but she's also getting her six-year molars, so that's not proof of anything.

On Friday she didn't start until closer to four, so she stopped naturally when her daddy came home at five.

Criminy.
