As a parent, you're able to add and edit certain information on your child's profile in the Playground App.
How to edit a child's information
On the Parent App, start on the Home screen and tap on the blue bar that says "View child's profile." You'll be brought to Student Profile screen, where you can see the information that's currently on your child's profile. To add/edit information or update their photo, tap the "Edit profile" button and then make your changes.
You can edit their name, birthday, address, allergies, and medications.
