What magazine subscription would you recommend?

We have to post presents and I thought this year to save on postage we can purchase a mag subscription for her. She's in prep. Do you think she's too young?

I don't like those Disney/licensed mags that have a million ads in them trying to make kids think they need all that stuff like bratz dolls etc.... don't like that.

I am thinking something along the lines of a kids national geographic, learning about animals, different topic each month....

Anyone?
