First swimming lessons can be exciting and terrifying, but this joyful and imaginative guide from Lisl H. Detlefsen, illustated by Madeline Valentine, shows young readers how to conquer the pool.

From what to wear (a bathing suit, of course!) to what to expect (no, your teacher will not be a mermaid), 1, 2, 3, Jump! covers the what-if’s and how-to’s of getting in the pool for the first time. There’s a lot to worry about (can I be sucked in the filter?) and even more to be excited about (when can I wear flippers?), and our narrator has thought of everything. By the time she’s ready, you to will want to jump in!
