Pitch: Users (age 2-4) mock-ride this rocking horse meets bouncy ball, which comes in 15 colors.
Payoff: “There’s tons of evidence that physical activity increases blood flow to all areas of the body, including the brain,” says Baird, the developmental psychologist. In other words: bouncing on Rody for half an hour won’t just tire your kid out before naptime—it could also help him retain his ABCs.
