But all this innovation is mostly being wasted on paranoid first time parents who need to obsessively check that everything is OK every five seconds (not judging, have been there).

What I need is a baby monitor that does one thing: wait a minute per month of age and see if there is still a problem. Stay silent until this threshold is passed.
