The Comforter on the go is a smaller version that you can take with you while traveling. This heartbeat comforter gives your child a sense of security and calmness on the road. You can easily attach the comforter to the Maxi Cosi or stroller with a strap. The comforter comes with a music box that plays two sounds: heartbeat and white noise. With a large button, you can turn on the music box, adjust the volume, and switch between the two sounds. The button is extra large, making it easy to operate the music box.
