Karen Katz uses bold folk art and lift the flap surprises to highlight a toddler's superior skills compared to a new baby. This approach builds confidence by celebrating simple milestones like using a fork or wearing big kid undies. Books in this family share a focus on autonomy and use interactive elements to empower young readers.

Reach for this book when your older child is feeling overlooked or frustrated by the arrival of a new baby. It is specifically designed to bolster the self-esteem of a toddler or preschooler who is navigating the shift from being the center of attention to becoming a big sister. Through interactive lift the flap illustrations, the book highlights the many things a big girl can do that a baby cannot, from using the potty to eating with a fork. The story focuses on themes of pride and personal growth, reframing the new sibling dynamic as a hierarchy of competence rather than a competition for love. It is perfect for children aged 1 to 4 who are in the midst of potty training or transitioning to a big bed. By celebrating these milestones, the book helps children find their new identity as a capable leader in the family, ultimately fostering a sense of protective affection toward the baby.
