My son was given a subscription to a great magazine by a dear friend--actually more like a little paperback book every month, called "Animal Baby".  It was wonderful--just his speed at age 2-3. It had big , bright photos, simple text, sturdy pages for a little guy and wonderful information about animals.  It had poems, finger-plays, short stories and matching games in every issue. 

  We've since subscribed to the next magazine they offer for a bit older crowd (3-7) called "Your Big Backyard" and it, too, has been great.  My son LOVES when a new issue comes in the mail.  My daughter enjoys the magazine as well.  Lots of info about animals, beautiful photos, little cut out books to make, jokes, stories, crafts to make and those stories with pictures in place of words here and there that kids can easily "help" read.  Excellent pre-Kinder.  Its great beyond the 4 & 5 crowd too though with lots of info about animal habitats, crafts and poems.
