The illustrations are perfect for a young baby (primary colors!) to an older pre-k child who likes to search for the items in the book. We plucked this one off of the bookshelf the other night and I had my 5 year old read it to me for a change. I was so proud of him as he sounded out the bigger words all on his own. Typically this a is a book we end our evening of reading with and I thought having him read it was the best way to end the night.
It is hard to believe that this book was first published in 1947 and that it is still a mainstay for children's books. I don't think this one will ever get old and even though our copy has tape holding the binding together, this will be a book I pack away for my kids to read/give to theirs.
