Should I be worried?

Given her gene pool, we already know she's wired for some sound...don't be OCD.

Winnie loves school -- she writes all of the time and plays school with her sister and reads and it's all good. So why should I be worried about the math?

The adding, the subtracting, the configuring of different numbers, same sum -- the counting. Counting of steps, counting of bites, counting items, counting of sips -- lots and lots of counting going on.

Be a natural stage of development -- don't be a need to count. Just don't.
