Your older sister recently had a baby and is confused about when she should wean her daughter. based on what you learned in physical anthropology class about the timing and characteristics of life history stages in humans, you tell her:

Here are the options for this question:
a. she should wean your niece by 6 weeks of age.
b. the neonatal period is the ideal time for weaning.
c. weaning marks the transition to juvenile status.
d. None of the above

And the answer would be: D. none of the above

The best time, for weaning, is when the child enter the age of 6-12 month, so option A and B is wrong and weaning mark the transition from infant status to Childhood status (not yet adolescent), so option C. is wrong
