Name game assistance

Vanessa
This may come as a silly question... but.. I'll ask it anyway lol 
So my husband and I have chosen names for our two twins (who are boys) but the question is how do you chose the twin that will carry that specific name. If we were having a singleton clearly we would know the name they would have, obviously. But for now all we go by is baby A and baby B. How do you chose the name for each baby? Should we just do a coin toss? Lol on who is who? Assistance or ideas needed lol 👶🏻👶🏻 😊
