Join your family
Step 1: Install the Nara Baby app
If you don't have the app installed yet, you can get it on the App Store or Google Play.
Step 2: Join your family
When you launch the app for the first time you'll need to create an account. Use the same email address that received your invitation and you'll be given the choice to join your family as soon as you're signed in.
Your family's invitation appears in the Family tab. Joining a family will replace your current family, including all its data.
