This sounds like a fine arrangement except it encourages a lot of crying. Let's examine the principles of behavior modification as it applies to crying behavior. Answers to these questions may help the confused parent figure out what to do about it. First, obviously, a child cries as a distress signal. That seems to be an inborn thing they all do.
Parents usually know when the cry represents a distress signal.
The distress signal even seems to have different qualities to it. That one becomes an extreme distress signal when the child is extremely hungry. There is the mild distress signal when the child is wet. They are all distress signals and it usually is not difficult to tell that they are. Crying is also a way of communicating.
