**Question:** All of the following are milestones at 7 months except-

A. Head and trunk control
B. Sitting without support
C. Standing with support
D. Running and jumping

**Core Concept:** Milestones in pediatric development refer to specific achievements that children typically accomplish during specific age intervals. These milestones serve as indicators of a child's overall development. In this context, milestones at 7 months encompass motor, cognitive, and social-emotional development.

**Why the Correct Answer is Right:** The correct answer, **D. Running and jumping**, is not a milestone at 7 months because these skills require full body coordination, balance, and increased strength, which are typically developed later in infancy and early childhood. At 7 months, infants are more focused on developing trunk control, sitting without support, standing with support, and grasping objects.

**Why Each Wrong Option is Incorrect:**

A. **Head and trunk control**: This milestone is essential at this age, as it allows infants to explore their surroundings, maintain balance, and engage in activities like rolling, sitting, and eventually standing.

B. **Sitting without support**: Sitting without support is a significant milestone as it enables infants to see more of their environment and engage in activities like reaching for objects and playing with toys.

C. **Standing with support**: Standing with support is an important milestone as it allows infants to interact with their environment, reach objects, and take their first steps towards walking.

**Clinical Pearl:** Paying attention to a child's developmental milestones is crucial for early identification of potential delays or referral to a pediatrician for further evaluation. Early intervention can significantly improve a child's overall development and quality of life.

**Correct Answer:** .
