I recently visited my parents and was searching their bookshelves for books that would interest my toddler. I came across this book and discovered that 30 years later I can still recite "big brown bear, blue bull, beautiful baboon, blowing bubbles biking backward..."
I loved this book as a child and my toddler loves it as well. It's fun to read, with large, colorful pictures and a silly story that certainly helps little ones figure out what sound a "B" makes. And they'll giggle all the way through as you try not to stumble over all those "Bs"!
