Question

Ruby is a healthy baby. Most of the time, she will tolerate when a stranger holds her. However, she prefers to be held by her father (her primary caretaker) or her babysitter (her secondary caretaker). Based on attachment theory, how old is Ruby likely to be?

a. about a year and a half
b. about one year
c. about six months
d. younger than three months

Answer 1

Ruby, based on attachment theory and typical developmental milestones, is likely about six months old. This age is consistent with her preference for primary and secondary caretakers and tolerance of strangers. Option c is the correct answer.

Step-by-step explanation:

Based on attachment theory, Ruby is likely exhibiting behaviors common around the age of six months.

At this stage, babies like Ruby are developing deeper attachments with their primary caretakers and may show some anxiety toward strangers, although they may still tolerate being held by them.

This period in infancy is when they also start to sit up, reach for objects, and enjoy vocal play. Ruby's preference for her father and her babysitter, her tolerance toward strangers, and her engagement in more complex interactions are characteristics of a six-month-old infant based on developmental milestones.
