The fun will stack up for babies and toddlers with the Count & Stack Crane construction toy from Fisher-Price. This push-along crane recognizes each of the 4 numbered blocks and lights up with fun sounds and phrases when they’re stacked or nested on top to teach numbers, counting, colors and shapes. Kids can press the music button or open and close the peek-a-boo lion’s door for more lights and sounds. The wrecking ball rattles and clicks for added sensory fun. Plus, all that pushing and crawling helps give growing muscles a workout.
