HOW TO GROW A DINOSAUR

Dinosaur fans expecting a new baby in the family now have a guide to big-siblinghood.

Esbaum and Boldt address readers directly in the second person and play up the humor of the ups and downs of having a baby. “Good news!” is followed by “Bad news!”: “Your mama’s hatching a baby!” but “Babies take their sweet time.” Mama dino carries a car seat with an egg strapped inside. Three pages show that the wait is too much for the impatient sibling: dad rescues the egg from a hammer-and-screwdriver threat. Of course, the egg hatches, then it’s time to wait until the new baby is big enough to do anything other than scream, eat, burp, sleep, and poop (this last causes the sibling to run away screaming). Gradually, the book continues, it will be your job to teach the baby how to be a dino, but be careful: babies are copycats, so watch your behavior. The digital T. Rexes are each a different color, the new baby pink with a purple pacifier, the older sibling orange with a blue shirt and toys that suggest it may be a boy.

While Esbaum and Boldt can’t address every aspect of having a new baby around the house, they hit the relevant highlights—the serious, the horrific, and the hysterical—and tenderly portray the growing bond between the two children.
