Does anyone have two separate monitor sets for two kids? We were going to go the Motorola route and have one monitor with two cameras but my husband is a very light sleeper so I am concerned that the switching between the two camera will keep him up at night. Then I decided to get two completely separate monitors for the two kids but now I worry about interference running between the two. Does anyone have this issue? Is there a way around it? Ugh...buying a monitor is much more difficult this time.
