While visiting a friend a few years ago, my daughter, Samantha, then 1, burst into a deep belly laugh. Sure, she’d cracked up before, but this time was different. No one was making faces at her or tickling her. No one was even laughing. Instead, what sent her into a fit of giggles was watching my friend’s dog jump up and down over and over again.
Though not quite as hilarious as the one-liners on Friends, a jumping dog was an unusual sight for Samantha -- and therefore worthy of a hearty chuckle. At about age 1, after months of mimicking the smiles and laughter of those around them, toddlers begin to reveal their own sense of humor. Their snickers mark an important developmental milestone and are a clear reflection of the smarts they’re acquiring.
“Sense of humor is directly linked to a child’s cognitive development,” says Kori Skidmore, Ph.D., a clinical child psychologist at Children’s Memorial Hospital, in Chicago. Humor develops as your toddler’s memory improves and she comes to understand (and recall) that the world operates in a certain way, with predictable order, structure, and patterns. When something nonthreatening happens that doesn’t fit those expectations -- like when she tries wearing your shoes -- she’s now aware of the incongruity and may find the act hysterical.
Laughter Is Contagious
Most children inherit their funny bone from their parents, experts say. Moms and dads who have a good sense of humor generally produce kids who do too. But a child’s environment has a tremendous influence as well. Caregivers who frequently laugh or joke around serve as role models, providing ample opportunities for a toddler to mimic humor.
“Even a young child learns to recognize humor when he sees his parents interact with him in ways that make him giggle, or when they recognize his early attempts at being funny and laugh with him,” says Doris Bergen, Ph.D., a professor of educational psychology at Miami University, in Oxford, Ohio. Playful interactions teach your toddler to appreciate the lighter side of life and to see the incongruity in everyday situations. When he laughs, use words to describe the situation (“That’s a silly face!” or “Elmo’s dancing is funny!”), so your toddler learns to apply language to a humorous event. If you laugh easily and use a warm, trust-building tone in games like peekaboo, your child will enjoy humor too.
