All the best things come in threes, not one, not two, but three, like the three-year-olds in this sweet picture book. As all parents know, three is a big year. Follow along as three friends learn new things in threes—from tricycles to triangles—take a dip in the pool, and play in the park with their friends! Of course, it’s not all fun and games. There’s a tantrum and then hugs all around as the three kids head to bed. This adorable picture book celebrating important life events is the perfect gift for third birthdays. Kids will love pointing out all the activities they can do now that they are three years old.
