Momo’s sick of smooches. “It goes on everywhere, all over the place,” he observes. “Especially mommies kissing babies.” Disgusted, the little monkey mounts an anti-kissing campaign. But it doesn’t make much difference; as he parades through the jungle holding a sign that says “No More Kissing!,” an anteater, wild boar, and rhino all try to lay one on him. His family is even worse, greeting one another, saying goodnight, and bidding goodbye with one kiss after another. So when his baby brother arrives, Momo knows what to expect. What takes him by surprise is what happens when he tries to soothe baby’s cry. As Momo explains, “ . . . a weird thing happened, by mistake I think. I kissed him.” Rendered in a lush, tropical palette, Clark’s (Roman Myths, p. 644, etc.) illustrations are redolent with detail. The opening spread depicts a mystified Momo sitting in a tree as the toucans and snakes, ducks and lions, butterflies and flamingos below show their affection. Later, Momo stands on a stool and declares his edict to his extended family. On the next page, humorous vignettes show him recoiling and running away from their persistent embrace. A series of smaller sketches show him producing toys, making faces, and juggling bananas as the baby kicks and cries. But the final illustration shows Momo holding his baby brother while the mother monkeys behind him quietly cheer. Says Momo of the kiss: “It was lucky no one was looking.” A sweet story sure to resonate with preschooler’s and parents everywhere. (Picture book. 5-8)
