The ability to make observations is even more important when working with infants and young children than it is when working with adults. the chief reason for this is that infants and young children:
a. do not like to be told that to do
b. are usually sicker than adults
c. enjoy human contact more than adults
d. cannot explain how they feel

D. Cannot explain how they feel

Explanation:

Children or infants in their stage of development cannot explain how they feel and so would need a lot more effort from the observer to understand what the young child may be feeling or going through

This is in sharp contrast to adults who can readily describe how they feel to the observer and the observer may not need to put in more effort in trying to understand or confirm this.
