SPECIAL SENSES
The baby cries, but the tears do not actually flow over the lids until he is three or four months old, and while the baby may fix his eyes upon objects and distinguish light from darkness, he will not wink nor blink when the finger is brought close to the eye. Vision is probably not complete until the beginning of the third month.
Infants are said to be deaf for the first twenty-four to forty-eight hours after birth, and some authorities hold that they are deaf for several days.
Taste is early developed, as a newborn baby will often repeatedly show a desire to taste sweet things, while if sour or bitter things are put to the tongue, it shows its displeasure.
