Newborn Infants' Sense of Smell: What Odor Do They Prefer?

Which of the following odors are newborn infants least likely to prefer?

a) The scent of their mother’s skin
b) The scent of amniotic fluid
c) The scent of their own soiled diaper
d) The scent of breast milk

Final answer:

Newborn infants are least likely to prefer the scent of their own soiled diaper (c) among the given options.

Explanation:

Newborn infants have highly developed senses, including a keen sense of smell. They are naturally drawn to scents associated with comfort and nourishment. The scent of their mother's skin (a) is typically familiar and comforting to them, as it reminds them of the warmth and security of the womb. The scent of breast milk (d) is another odor they are likely to prefer, as it signals a source of nourishment and sustenance.

The scent of amniotic fluid (b) is also familiar to newborns as they have been surrounded by it in the womb. While it may not be their top preference, it is not an unpleasant odor to them.

On the other hand, the scent of their own soiled diaper (c) is likely to be the least preferred. Infants may find this odor unpleasant or discomforting, as it signifies the need for a diaper change and potential discomfort.

In summary, the scent of their own soiled diaper is the least likely to be preferred by newborn infants among the given options, as it is associated with discomfort and the need for attention.
