My little monster is just 19 months, but she has more fun with colorful, counting book than I'd ever imagine. Ten Friendly Fish is full of vivid pictures of sea life that she just adores. In fact, her limited vocabulary includes "oppa" (octopus), which I'm certain is a direct result of this book. With each turn of the page, one more fish gets distracted by a new sea friend until the very end when the one lone fish is once again reunited with all of his original buddies at their party in the sea! Great for learning sea life names, looking at brilliant pictures and of course, counting! Tarbett also has a similar book about Ten, Wriggly, Wiggly Caterpillars, if that's more your style! We found Ten Friendly Fish on Amazon for $18.95.
