Here's how it works: You list as many names as you want and the next person gives a name that sounds like a sibling.
For example.. Person 1 says: Leo, Henry, Emma Person 2 adds: Oliver and then lists a few names.
Person 1 can tell you if they want a boy or girls name. If they don't specifically say which one you can choose.
To start: Lila Claire, Aidan Levi, Scarlett Poppy and Ruby Quinn. Sibling is a girl!
