Methods and apparatuses monitor and evaluate the movement and sounds of an individual in a sleeping structure to identify individual movement and sound activities that are outside acceptable movement and sound tolerances. Similarly, the methods and apparatuses monitor and evaluate the gases surrounding the individual and the temperature and humidity to identify environmental conditions that are outside acceptable environmental tolerances. The methods and apparatuses constantly and dynamically change the acceptable movement and sound tolerances and the acceptable environmental tolerances based on the age of the individual and based on historical monitoring of the movement and sounds of the individual, historical monitoring of the gases surrounding the individual, and historical monitoring of the temperature and humidity surrounding the individual. The methods and apparatuses cause the input/output device to provide an audible warning and at least one electronic message warning based on movement, sound, and environmental conditions being outside acceptable tolerances.
