Just like Millie
(Book)

A little girl and her mother move into a new apartment. Initially, the child is too shy to make eye contact with their neighbors, too shy to agree to playdates, and too shy to join a group of kids at a bookshop's storytime. One day, she and her mom visit an animal shelter and return home with Millie, a "not too big, not too small dog." Quiet but friendly, Millie approaches every neighbor they see outdoors. Gradually, after watching Millie in action, the girl begins to let go of her fears and, one day at the dog park, gathers the courage to befriend another child and her mother, who are sitting on a bench nearby.
