In the parent's menu, verify that the kid whose schedule you want to copy from, and the kid you want to add the schedule to, are listed there. If one is missing, you'll need to add it.
Go to Kid Menu> [Schedules] and tap the [+] button.
Select [COPY A SCHEDULE] from the menu.
Select [X] to exit the menu.
Create a name for the new schedule and select the schedule that you would like to copy.
By default, your new schedule will have the same name as the copied schedule, unless you enter a new name.
Tap [Save] if you are using an iPhone, or if you are using an Android Phone.
