Just swinging the smartphone will cause the baby 's favorite rattling sound to flow!
You can play together as soon as there are no complaints at hand.
Because you can play while face to face, babies are also very safe!
Besides rattles, a fun maracas version and handbells with cute tones are also available!
Not the same sound, but various kinds of sounds flow at random,
I feel like I'm really shaking the rattle!
* Since it is also a tap, you can use it by tapping the screen if it is difficult to shake
