Elizabeth Verdick has been writing books since 1997, the year her daughter was born. Her two children are the inspiration for nearly everything she writes. Before becoming an author, Elizabeth edited books for children and parents.

These days she writes books for babies, toddlers, teens, and every age in between. She especially loves creating new board books. The Happy Healthy Baby® series is designed to capture the interest of the littlest readers. Elizabeth’s Toddler Tools® series helps young children and their parents cope with those tough times and transitions that happen every day (like naptime and bedtime). In the Best Behavior® series, she helps toddlers reach new milestones and improve their day-to-day behavior.

Elizabeth also enjoys getting the chance to look at the funny side of life in the Laugh and Learn® series, which helps kids ages 8–13 get a handle on the social-emotional skills they’re developing throughout the elementary and middle school years. She’s also coauthor of The Survival Guide for Kids with Autism Spectrum Disorder (And Their Parents), which offers kids with autism spectrum disorder (ASD) their own comprehensive resource for both understanding their condition and finding tools to cope with the challenges they face every day.

Elizabeth lives and writes near St. Paul, Minnesota.
