You notice that a six-month infant is not awake, not moving, and not breathing normally. The infant's skin is blue. What would make you suspect the infant is unconscious from choking.

The main pointer to choking would be the child's skin.

Explanation:

The child's skin looks blue due to the blood. Blood that is rich in oxygen looks red, while blood with little to no amounts of oxygen appears dark blue. The dark blue, poorly oxygenated blood is showing through the skin, warning the person that the infant is choking.
