Is she really old enough????

So I spoke with the school district yesterday and it's official. Mia will begin pre-K at the elementary school in August! Doesn't seem like all that long ago that we were waiting and waiting and waiting for her arrival. And in the grand tradition of girls she arrived fashionably late-10 days late.
She has been waiting to be able to go to school and she will be going to a school which just opened this year. It is about 1 1/2 miles away. One of her best friends-Shaley-started Kindergarten there this year and Mia is so excited to be able to go to school with her. She will be attending the 1/2 day morning program 5 days a week.
Doesn't seem like she's old enough already does it?
