Close your eyes and listen to the gentle music of the Rattle Nighthawk. What does it sound like? Rattle Nighthawk is a wooden rattle with a sound reminiscent of Poland's native birds! Children can roll, shake or spin the toy, improving their fine motor skills. The unique sound is made by two different kinds of wood clinking against each other.  The gentle noise is soothing for both children and adults. A simple baby toy that won't overstimulate your baby's developing brain.
