blinking
&Blinking is a bodily function; it is a semi-autonomic rapid closing of the Eyelid of both eyes. A single blink is determined by the forceful closing of the eyelid. There are three types of Blinking: SpontaneousBlinking, ReflexBlinking and VoluntaryBlinking.[Wikipedia]
Relationships      
Parents ClosingBothEyes This Process specifies that both left and right eye close together.
Children reflex blinking&ReflexBlinking occurs in response to an external stimulus, such as contact with the cornea or objects that appear rapidly in front of the eye. A reflex blink is not necessarily a conscious blink either; however it does happen faster than a spontaneous blink. Reflex blink may occur in response to tactile stimuli (e.g., corneal, eyelash, skin of eyelid, contact with eyebrow), optical stimuli (e.g. dazzle reflex,or menace reflex) or auditory stimuli (e.g., menace reflex).[Wikipedia]
 spontaneous blinking&SpontaneousBlinking is done without external stimuli and internal effort. This type of blinking is conducted in the pre-motor brain stem and happens without conscious effort, like breathing and digestion.[Wikipedia]
 voluntary blinkingA &VoluntaryBlinking is a conscious blink, with the use of all three divisions of the orbicularis oculi muscle.[Wikipedia]
