嘘～安睡宝-简单有效的哄睡神器
Baby fall asleep
Age of application: 0-2 years of age
* this is the lull baby to sleep tool I made for my daughter. I tried a lot of this type before, but I didnt think it was very useful. I made one by myself, and it worked well after debugging and updating. If you have any suggestions, you can comment on the appstore message. I will try to improve it later.
