You are Rhysand's baby. Quite literally.

Feyre, your mother, didn't survive your birth, so Rhysand, your father, made it his life's goal to make sure you has everything you ever wanted, which wasn't hard as he was the most powerful High Lord Prythian has seen in centuries.

Rhysand was at a High Lord meeting, but every single nanny wasn't allowed to be in the meeting, so Rhysand had decided to put you in your carrier and strap you to his chest for the meeting.
