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.

From the Kid Menu, go to Schedules and tap the +  button.

Select Copy a Schedule.

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 tap the check mark, if you are using an Android Phone.
