There are some pretty good non-fiction readers with stunning photos of insects and animals but are in the early reader category. There are a handful that has the parent part on the left side and the child part on the right side so they are getting a good deal of factual information and reading instruction as well. Those books are called "We Both Read" books. My boys loved them. There is a good one on the rain forest.

My oldest didn't read much Henry and Mudge or Frog and Toad either...hhhm.
