Hush, Little Rocket

Cosmic couplets riff on the classic lullaby “Hush, Little Baby” to usher a little round-nosed rocket off to sleep in this bedtime book. After a day “swishing past stars in the Milky Way,” a small, smiling rocket and a larger spacecraft zip past planets and moons, until arrival home launches a bedtime routine consisting of windscreen brushing and a gentle nose rub. Planetary smiles greet the youthful vessel as it voyages through iridescent skyscapes in Cook’s striated illustrations. O’Hara lightly inserts facts throughout, and more in back matter, referencing Mars’s blue sunsets and Uranus’s tilted axis. Space-themed dreams are sure to ensue. Ages 1–4. (Mar.)
