Let’s be honest–finding just one book to put on the list written and illustrated by Bill Martin and Eric Carle was extremely difficult. Eric Carle is loved the world over for his illustrations, because they are unique and colorful. This book also covers animals–which all toddlers love–and has a great rhyme scheme. Rhyme schemes are very important for toddler development, because they help young children see the patterns between pieces of words and their sounds. Eric Carle’s books have been loved for three generations, so get your toddler started on one today.
