From what to wear (a bathing suit, of course!) to what to expect (no, your teacher will not be a mermaid), 3, 2, 1 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 into 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!
