## **Core Concept**
Transitional objects are items used by children to provide a sense of security and comfort, often during times of stress or uncertainty. They are a normal part of child development. The concept of transitional objects was first introduced by pediatrician Donald Winnicott.

## **Why the Correct Answer is Right**
Transitional objects typically appear around the age of 6 to 12 months but can be most notable and prevalent from 12 to 24 months. This period is crucial for child development as it coincides with the child's growing awareness of their environment and their ability to differentiate between their caregivers and other objects or people. The use of transitional objects, such as a favorite toy or blanket, helps the child transition from a state of complete dependence on the caregiver to more independent states.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because transitional objects usually start to appear a bit later than this age range.
- **Option C:** This option is incorrect because, although some children may still use transitional objects beyond this age, the peak period for their introduction and use is earlier.
- **Option D:** This option is incorrect because it suggests a much later age range than when transitional objects typically first appear.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the presence of transitional objects is a normal and healthy part of child development. Pediatricians and healthcare providers often encourage parents not to worry about these objects, as they can provide comfort and help in the child's emotional development. Typically, children outgrow the need for transitional objects as they develop more mature coping mechanisms.
