For those with multiple children (or expecting your 2nd), do you have a separate monitor system for each kid’s room, or do you have a camera in each room that all send to one monitor? My daughter will be 20 months when our new LO comes in March, and I’m torn if we should just buy a 2nd camera to put in the new baby’s room (our current monitor supports multiple cameras but you can only view one at a time) or wondering if we should get a whole 2nd system so we can see both kids at the same time without having to switch back and forth between 2 cameras. Any advice?
