Share a room or not?

You have a 6 year old son, 4 year old daughter and 2 month old son.
The 2 month old is currently sleeping in a bassinet in your room but you've decided it's time to figure out his sleeping arrangements. 
Your 6 year old has a room 12x12 and your daughter has a room 10x8. 
Would you..
A. Put the crib and such in the boys room and have them share
(Possible issues such as keeping the room quiet for baby's naptime and bedtime etc..)
B. Have the two oldest share the 12x12 room and put the baby in the 8x10 room.
