Hi there!
I have an older DD8 and a DS3. DS3 is fascinated with numbers. We recently took a long car trip and he kept himself amused with a calculator for most of the ride. He also loves planets and the solar system. Tonight I had to look up where the dwarf planets Ceres and Eris are located so he can include them when he lists the planets in order (if anyone's interested, Ceres comes after Mars and Eris is out past Pluto). His favorite toy is the Quadrilla marble run and he likes to invent his own structures.

He'll be starting at a Montessori preschool this fall, and I hope they can keep up with him.
