Do I need two white noise machines for twins?
One, if the twins share a room. A second only if they sleep in separate rooms or one travels in the diaper bag.
Verdict
Buy one
Why
White noise fills a room, not a crib, so one machine covers two babies sleeping ten feet apart. Its real job with twins is masking the other baby's 3 AM grunting, and one unit does that fine. Two machines in one room just make the room louder.
Safety note
Keep the machine across the room from the cribs, not on the rail, and run it at a conversational volume.
