My next door neighbor received a different kind of Safety 1st monitor and now we are both receiving the others baby... meaning that during the night when I think that I am getting up with my baby it turns out that I am hearing the other baby and when she thinks that she is hearing her baby it is mine. We have tried switching channels and everything, but nothing works. I have tried to find a phone number for Safety 1st but am unable to do so. If I could find the number then I would let them know what I think about their monitors.
